What are the essential stages of full cycle game creation? It’s a question worth answering precisely, because skipping or collapsing stages is one of the most common causes of delays and budget overruns in the industry. Full cycle game creation follows a clear sequence, and teams that lose track of which stage they’re in tend to pay for it in missed milestones and unrecoverable costs.
At Kokku, we’ve mapped this pipeline across projects of every scale, from proof-of-concept sketches through gold master certification, working alongside major studio partners on the entire development pipeline. What follows is a stage-by-stage breakdown of the full production cycle, with the deliverables and role clarity that make the difference between shipping and stalling.
The 8 essential stages of full cycle game creation
Understanding what are the essential stages of full cycle game creation starts with recognizing that each stage has a defined deliverable and a clear owner. The eight stages are: concept, pre-production, vertical slice, production, alpha, beta, certification, and launch, with live ops extending the cycle well beyond ship date. Miss a gate, and the cost doesn’t stay local. It compounds forward. For a practical breakdown of these phases, see an industry overview of the stages of the game development process.
The foundation: Concept, Pre-Production, and the Vertical Slice
Turning a raw idea into a validated proof of concept
The concept stage has one job: prove the core gameplay loop is actually fun. The deliverable isn’t a polished pitch deck. It’s a small, playable prototype that answers the question every publisher and internal stakeholder needs answered before committing resources. Core creative leads, typically a product or creative director alongside a small multidisciplinary team, own this stage. For indie projects, it runs weeks to three months. For AAA titles, expect up to six months.
The acceptance bar here is deceptively simple: does the game feel worth making? If the answer isn’t a confident yes, no amount of production muscle will fix it downstream.
Pre-Production: the GDD, prototyping, and the Vertical Slice Gate
Pre-production is where ambition gets translated into a blueprint. The game design document (GDD) defines mechanics, narrative architecture, systems, and level structure. It’s the single source of truth that keeps every discipline aligned through production. Without it, teams build on assumptions that quietly erode alignment and eventually surface as conflict.
The most important gate in this stage is the vertical slice: a playable cross-section of the finished game, covering the main menu, one complete level, and the core mechanic loop. For indie and mid-sized projects, this slice is often rough but functional; AAA pipelines typically expect a more polished, representative segment, sometimes 15 to 60 minutes of near-shipping-quality gameplay. In either case, the acceptance criterion isn’t cosmetic. It’s de-risking. The vertical slice proves the team has the technical and artistic capacity to build the full product before committing to a full production runway. Choosing the right prototyping tools during this stage can dramatically accelerate validation and stakeholder buy-in.
Production, Alpha, and Beta: where the game gets built
Feature Complete (Alpha): every system Is in, rough edges allowed
Alpha means every feature is functional and testable. UI, progression systems, combat, analytics, accessibility layers, all of it must be in the build. Content can be rough, but nothing can be missing. Producers managing the development pipeline own this milestone, with discipline leads accountable for feature delivery within their area. For mid-sized projects, alpha typically arrives just past the halfway point. In a AAA pipeline, reaching alpha takes roughly one year of full production.
The trap teams fall into here is conflating “functional” with “polished.” Alpha is not the time for cosmetic fixes. It’s the time to confirm that each system works at all.
Content Complete (Beta): the game runs start to finish
Beta is a distinct milestone from alpha, and it’s worth treating it that way. All planned content is in. The game is playable from the opening screen to the credits. Tutorialization is fully implemented, localization strings are locked, and the project is ready for vendor QA. Beta should arrive 8 to 12 weeks before launch for smaller projects, and roughly nine months into production for a AAA pipeline.
The most common failure at this stage: teams enter beta with an unstable build. An unstable build compresses the QA window and creates a cascading delay that pushes the launch date, it rarely recovers it.
QA, platform certification, and locking the release candidate
What a rigorous QA pipeline actually tests
A well-run QA pipeline tests across four pillars:
- Functional testing, confirms there are no crashes or softlocks
- Usability testing, validates that gameplay flow is intuitive without external explanation
- Compatibility testing, covers the full device and platform range the title targets
- Performance testing, measures frame rate, load times, and memory consumption against platform thresholds
A bug priority list runs in parallel: game-breakers at the top, cosmetic issues at the bottom. For mid-sized projects, this phase runs two to six months.
Platform certification: the gate most teams underestimate
Console certification for PlayStation, Xbox, and Nintendo is a formal submission process governed by each platform holder’s technical requirements checklist. The release candidate submitted for review must be crash-free, must handle suspend and resume cleanly, and must display the correct branded controller button imagery. Sony and Nintendo typically require four to eight weeks per submission round, and a single critical bug resets the clock. For AAA projects, the certification and final polish phase runs approximately three months. Teams that arrive at certification carrying unresolved P1 bugs pay for it in resubmission cycles and delayed revenue.
When producers and leads understand project team roles and responsibilities, the certification pipeline runs more predictably, clear ownership reduces handoff errors and resubmissions.
Launch, Live Ops, and keeping the game alive post-dhip
Day-One deployment and the first-week stability window
Launch is not the finish line, especially on live-service or multiplayer titles. The day-one deliverables cover the final release build, active community infrastructure, and uptime monitoring. Player-discovered bugs that survived QA need patch cycles within days, not weeks. Strong first-week stability matters because early retention patterns are difficult to reverse once they’re set, which makes operational readiness on day one non-negotiable.
DLC, Patch Updates, and sustaining a live service game
Post-launch, or post-production in pipeline terms, is its own production cycle in miniature. Patch updates address player-reported issues. DLC expands content, reengages the player base, and sustains revenue between major titles. The critical structural requirement here is separation: the live ops support pipeline must run independently from any new production work, or both efforts degrade.
This is where co-development partnerships become genuinely strategic. An external team absorbs the live ops workload while the internal studio focuses on the next project, without either track compromising the other.

Map your project before you build It
The eight essential stages of full cycle game creation form a repeatable system: concept, pre-production, vertical slice, production, alpha, beta, certification, and launch, with live ops extending the cycle beyond ship date. Knowing the deliverable and owner at each gate is what separates projects that ship from projects that accumulate technical debt and miss windows.
For teams mapping out the full production cycle, the right co-development partner owns each gate the same way an internal team would, because they’ve shipped through all of them. At Kokku, that’s exactly the role we take on: whether that means co-developing production, owning QA, running certification, or sustaining live ops after launch.
