How Full-Cycle Game Development Contracts Work

Full-cycle development means one studio takes the project from concept through production to a shippable build, usually with their own producer, leads and pipeline. You supply the vision, the funding and the approvals; they supply the team and the process. It is the right model when you have a concept and a budget but not a studio, and the wrong model when you have a team that just needs extra capacity, which is what co-development is for.

The commitment runs in both directions. A full-production partner is carrying your project for a year or more, so their business stability matters as much as their portfolio. Ask how many projects they run in parallel, how long their average client relationship lasts, and what happened the last time a project overran.

How milestone contracts work

Full production is normally structured as a milestone contract: a schedule of dated deliverables, each with acceptance criteria, each triggering a payment. The quality of the contract is entirely in the acceptance criteria. "Vertical slice complete" is not acceptance criteria; a named feature list, a target platform, a frame rate and a build that runs unattended for ten minutes is.

Standard structure to expect:

• Pre-production milestone producing a technical design document, an art bible and a revised schedule, priced separately and terminable
• Vertical slice with a defined feature list on the lowest target platform
• Alpha and beta gates with content-complete and feature-complete defined explicitly
• Certification and submission milestone if you are shipping on console
• A post-launch support window with a defined scope and response time for critical bugs

What to verify before committing

• Shipped titles they took end to end, not titles they contributed art or QA to. Ask directly which role they had.
• Whether they hold current developer accounts and devkits for your target platforms.
• Who the named producer and leads are, and whether they are free for your dates or finishing another project.
• Payment structure. Milestone payments on acceptance protect you; large upfront payments do not.
• IP assignment on payment, source code escrow if the budget is large, and what happens to the code if either party terminates.
• Their post-launch position. A studio that treats launch as the end will not be helpful in the first patch week.

Where full-production deals go wrong

The dominant failure is approval latency on the client side. A studio can only move as fast as its feedback loop, and full production contracts routinely slip because milestone reviews took three weeks instead of three days. Before signing, decide who on your side has authority to approve a milestone, and give them the calendar time to do it.

The second is scope added without schedule. Every accepted change should carry an explicit cost and date impact in writing at the moment it is accepted, not at the end of the milestone when the slip is already real.

For the difference between this model and embedding a partner in your own team, read full-cycle vs co-development, and sanity-check the schedule with the timeline estimator.
