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

Wwise

  • Tier eligibility is set by production budget: the free Indie plan requires a production budget under $250K
  • A production budget between $250K and $2M requires the Pro plan, starting at $8,000 US
  • A production budget above $2M requires the Premium plan, starting at $27,000 US, or Platinum starting at $52,000 US
  • Licence pricing is per title and per platform rather than a flat studio fee, and the headline figures are starting prices
  • Premium plug-ins and the Wwise DLC licence are optional paid add-ons on Pro and Premium rather than included
  • Source code access is only available with a support package
  • On the free Indie plan there is no paid support option at all, only community Q and A
  • Royalty-free status is optional rather than automatic on the Pro plan
