Which tool for which job
Diversion wins when you want a hosted, game-focused version control system and qualify for the free Indie plan or can pay per seat.
Summer Engine wins when you want to build and ship a real 2D/3D game with an AI-first engine rather than only generate assets for Unity or Unreal.
