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
Lumberyard
- aws.amazon.com/lumberyard now redirects to the AWS homepage; Amazon Lumberyard is no longer offered as an AWS product
- The engine's successor is the Open 3D Engine, governed by the Open 3D Foundation rather than AWS, so migration means moving to a differently governed project
- No Lumberyard-branded documentation, download or support commitment remains at the original AWS product URL
