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

Flax Engine

  • Flax charges a 4% royalty on game earnings above $250,000, assessed per calendar quarter
  • Free use is granted for non-commercial or educational usage; commercial releases fall under the royalty
  • Users must accept the Flax Engine End-User License Agreement before using the engine or its tools, so it is not an OSI open source licence despite the source being on GitHub
  • Non-game uses such as in-house tools or SaaS products need a custom licence negotiated with the vendor, and no rate card is published for per-seat or flat-fee options
