Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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

OGRE

  • No commercial support tiers; open source community support only
