Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
CryEngine
- A royalty of 5% of Gross Receipts is payable to Crytek on every game built with CRYENGINE
- Royalties are waived only on the first USD 5,000.00 of Gross Receipts per year per game
- Royalties are calculated at source on gross receipts before any publisher or platform deductions, so a developer receiving 70% of USD 100,000 still owes USD 4,750
- Military projects, gambling, simulation, science, architecture and serious games are excluded from the standard licence and are not covered as Games
- The licence forbids combining CRYENGINE with code from other game engine providers
- Supported platforms are limited to those Crytek announces at its sole discretion, listed in the agreement as Windows, Linux, PlayStation 4 and Xbox One
- Support is only provided against payment of a separate Support Fee that Crytek may change at its sole discretion
- Crytek may modify the licence agreement at any time, with the only remedy for disagreement being to stop using CRYENGINE
Ren'Py
- Desktop support is limited to Windows 10 and later on x86_64, macOS 10.10 and later on x86_64, and Linux on x86_64 or Arm
- Android and iOS are secondary platforms and development must be done on one of the three desktop platforms
- Browser builds require WebAssembly support and Ren'Py states this platform remains Beta
- Text support covers languages that do not require ligatures, with only some ligature-requiring languages supported
