The short version

  • Each has a real cost: Cocos2d-x cocos2d-x is MIT licensed with no commercial tier, and the vendor's own site directs users toward its newer engine, Cocos Creator, as the actively developed product, leaving Cocos2d-x without a first-party paid support or upgrade path.; Unreal Engine 5% royalty triggered on any project exceeding $1 million in gross revenue across all revenue sources
  • They diverge on capability: Cocos2d-x covers 2D rendering, Unreal Engine covers Real-time ray tracing.
