Outsourcing, Co-Development & Full Cycle Development in the Global Video Game Industry

Modern video game production runs on three connected external development engagement models: specialised outsourcing, co-development, and full cycle development. Most AAA titles draw on all three of these models at various points in the development pipeline, rather than committing to a single approach all throughout.

At Side, we work across all three, helping studios and publishers find the right model, or blend of models, for a title. That same spectrum is also what powers the localisation and globalisation work that carries a title into new markets around the world.

What Are the Three Video Game Outsourcing Models?

Video game outsourcing breaks down into three common models: specialised outsourcing, co-development, and full cycle development. The difference comes down to how much of the build a partner takes on. Specialised outsourcing covers specific project- and task-based work scoped by the development studio, co-development means sharing ownership of a system or faeture inside the studio's pipeline, and full cycle development fully gives the primary developer's role to the partner. These three separate service categories serve as points along a single game development spectrum.

Specialised outsourcing sits at the narrowest end of the spectrum. Here, a partner takes on one defined piece of the work, such as quality assurance, localisation, audio, art, or player support, built to a specification the studio has already set. Creative and technical ownership stays in-house, while the partner works toward agreed milestones and acceptance criteria. It's often the first step studios take toward a longer-term partnership with a service provider.

Co-development goes a step deeper than specialised outsourcing. Instead of handing off a defined deliverable, the service provider’s team works from inside the studio's own pipeline, sharing ownership of a feature or system side by side with the internal team. It's a strong fit when a studio needs to scale a specific system, such as multiplayer, live ops, or a new platform port, without building an entirely new internal team to do it.

Full cycle development goes all the way. A partner such as Side steps in as the primary developer, taking a build from its earliest concept through to a live title. This model is built primarily for publishers that need a proven, standalone team to run with a project from end to end, rather than support a team that already exists.

Understanding the broad spectrum of game development models is especially important in such a rapidly evolving industry. This rapid growth is clear in the most recent market data:

• Market.us estimated game outsourcing services at $1.87 billion in 2024, projecting growth to $9.04 billion by 2034, a 17.1% CAGR. by 2034, a 17.1% CAGR.
• Verified Market Research put the broader global game development outsourcing services category, including co-development engagements, at $8.97 billion in 2025. This number is projected to grow to $22.78 billion by 2033, a 14.3% CAGR.
• Newzoo's 2026 Global Games Market Report projects the total global games market, not outsourcing specific, at $213.9 billion in 2026, a 6.1% increase year-over-year, with Asia-Pacific accounting for $100.7B billion of that figure.

Across all three estimates, Asia-Pacific leads the market by share. This is the diverse demand base the video game outsourcing, co-development, and full cycle development market exists within.

The External Development Spectrum

What separates specialised outsourcing, co-development, and full cycle development comes down to three things: how much work is scoped, how deeply the partner integrates, and who holds ownership of the result. Presented side by side, the differences are easier to see.

Note: Here, ownership refers to the development and successful delivery of a feature or system, not ownership of the underlying intellectual property.

External development works as a spectrum rather than a binary choice between insourcing and outsourcing. In practice, partnerships rarely begin at the most integrated point on that spectrum. Many game development projects start with a narrowly scoped, specialised outsourcing engagement. As trust and results accumulate, the partnership may move toward co-development or, in some cases, full cycle ownership of an entire title.

Real-world cases back up that progression. Looking across a set of well-documented outsourced PC ports and remasters, the strongest outcomes had little to do with vendor size or geography. What mattered instead was scope clarity, clear acceptance criteria, and shared ownership – the same three factors behind the Scope, Integration, and Ownership categories above. Add a sharply defined brief, valid source assets, and the willingness to delay launch if quality gates weren't met, and that combination consistently produces the best results.

The Modern AAA Hybrid Game Outsourcing Model

Most modern AAA productions do not choose a single engagement model. Instead, they run a hybrid: an internal core team, one or more co-development partners embedded on specific systems, and specialised outsourcing vendors covering areas such as asset production, quality assurance, and localisation – all running with varying levels of overlap throughout the development pipeline.

Our own Chief Marketing Officer at Side, Kaley Hurst, served as guest author of the XDS 2026 Insights Report, which names external development an established pillar of modern game production. This research also found that communication friction rose 15% year-over-year on both sides of the relationship, among developers and publishers as well as service providers, making it a stronger predictor of engagement risk than vendor geography or size.

A clear pattern is showing up across that hybrid structure in the form of a three-layer vendor model:

1. A lead co-development or engineering partner
2. A dedicated quality assurance and compliance partner
3. One or more art, localisation, or audio specialists

Across the industry, studios often choose this model for the specialised expertise it brings, the ability to scale, and the cost efficiency it offers. Large co-development studios that build major gameplay systems, multiplayer modes for AAA publishers among them, are a good example of the pattern in practice, though the exact mix shifts from title to title.

None of these arrangements manage themselves, no matter which layer a vendor sits in. What separates a setup that holds together from one that doesn't usually comes down to the same few things:

• Defined milestones
• An experienced outsourcing lead
• Documentation and communication channels agreed on upfront
• A clear cycle of feedback and iteration
• IP and legal agreements at every layer

When these fall away, communication friction is rarely far behind.

How Does This Spectrum Power the Video Game Industry Today?

All three engagement models are also what make video game globalisation possible. Specialised outsourcing typically carries the bulk of translation, localisation QA, and regional compliance work; co-development can extend to owning market-specific features such as regional live ops calendars and payment integrations; and full cycle development can build a title or DLC region-first from concept rather than adapting it afterward.

That globalisation work covers more ground than translation alone. It spans:

• Culturalisation and localisation across both text and audio
• Technical localisation (UI, menus, in-engine text)
• Legal and regulatory compliance
• Platform and marketing localisation
• Live operations
• Regional business adaptation

Handling every one of those disciplines internally would slow most productions down, so publishers tend to lean on external specialists for the tasks that call for market-specific knowledge such as voice recording, cultural consulting, audio and art localisation, UI adaptation, and the ongoing work of regional customer support and community management once a title is live. the largest publishers follow this pattern. Ubisoft, EA, Activision Blizzard, Riot Games, and Tencent all rely on networks of localisation vendors and regional service providers rather than building every regional capability in-house.

Newzoo's 2025 Global Games Market Report projected a $188.8 billion global games market for 2025, with players spread across every major region. Asia-Pacific held the largest share at $87.6 billion, followed by Europe at $33.1 billion, Latin America at $8.3 billion, and the Middle East and Africa at $7.1 billion. Because no single region holds a majority of that revenue, reaching players beyond a studio's home market is a smart and necessary business move. Doing it well takes real regional expertise and a clear understanding of what players in each market expect.

Building games for players in so many markets at once is changing how localisation is approached. AI-assisted translation is now paired with human post-editing, since AI can keep up with the growing volume of content but still misses the cultural nuance and tone that make a game feel native to a region. Continuous localisation is built directly into development pipelines rather than added at the end, because live updates and ongoing content mean localisation can't wait until after launch. Regional personalisation is going deeper than simple language swaps too, as players increasingly expect a game built to reflect their unique play styles and cultural environments.

Our service areas, including Localisation, Player Support, and Community Management are built to help video game productions scale globally. The three-model spectrum is the infrastructure that turns a title into a genuinely global product.

Frequently Asked Questions

What Is Video Game Outsourcing?

Video game outsourcing means bringing in external studios or specialists to handle part of a game's production, rather than building every function in-house. Quality assurance testing, localisation, art, audio, and player support are among the most common examples. The practice covers a wide range, from narrowly scoped, task-based work all the way to fully embedded co-development and full cycle development, where an outside partner owns a build from concept through to ship.

What's the Difference Between Outsourcing and Co-Development?

Outsourcing typically covers a defined scope of work built to a spec the client controls, while co-development places an external partner inside the studio's own pipeline, sharing ownership of a feature or system with the internal team. Think of co-development as a deeper point on that same spectrum, not a different kind of engagement altogether.

What Is Full Cycle Development?

Full cycle development is where a partner takes on the responsibility of video game development from beginning to end. Rather than delivering a single defined service or feature, an external partner such as Side steps in as the primary developer, owning a title's production from concept all the way through to a shipped, live game.

Why Do AAA Studios Outsource Game Development?

Outsourcing lets AAA studios scale specialist capacity in quality assurance, localisation, art, and audio without growing full-time headcount, tap regional expertise for globalisation, and manage schedule and cost risk across a production's lifecycle. That's why most modern AAA productions run a hybrid, pairing an internal core team with co-development partners and specialised outsourcing vendors at the same time.

How Does Video Game Outsourcing Support Globalisation?

Much of what makes a title genuinely global runs through outsourcing partners, including services such as translation, localisation QA, regional compliance, platform localisation, and market-specific live ops or payment integrations. No single region accounts for a majority of the global games market, which makes this kind of external support a structural requirement for studios operating at scale.
