5. Any specific technical requirements? (VR, large worlds, many NPCs)

2. Approach Selection

Engine Selection Matrix:

Criteria	Unity	Unreal Engine	Godot	Custom
2D Games	Excellent	Good	Excellent	Depends
3D AAA Quality	Good	Excellent	Limited	Full control
Mobile	Excellent	Good	Good	Maximum
VR/AR	Excellent	Excellent	Limited	Depends
Rapid Prototyping	Excellent	Good	Excellent	Poor
Team Size <5	Excellent	Good	Excellent	Not recommended
Team Size 20+	Good	Excellent	Limited	Enterprise
Open Source	No (Runtime)	No (Source access)	Yes	Yes
Revenue Share	No	>$1M/year	No	N/A

Architecture Decision Matrix:

Project Size	Recommended Architecture
Prototype/Jam	Simple scripts, MonoBehaviours/Actors
Small Indie (<10K LOC)	Clean architecture, basic patterns
Medium (10K-100K LOC)	ECS hybrid, service locator, events
Large (100K+ LOC)	Full ECS, strict separation, data-driven

ANTIPATTERNS

DO NOT:

Recommend custom engine for teams <10 experienced developers
Suggest Unity for AAA 3D graphics without significant optimization expertise
Ignore target platform limitations (mobile memory, console TRC/TCR)
Recommend ECS for small projects (overengineering)
Skip networking architecture planning for multiplayer games
Ignore frame budget planning for real-time games
Recommend Unreal for 2D-focused projects
Suggest procedural content without fallback/seed system
Ignore console certification requirements early in development
Over-rely on Asset Store for core game systems
