Thank you! Funnily enough, an earlier build of sang is one of the games I've been using to test the engine.
I'll probably have to skip it for now, because a lot of entities and lights are spawned with the map script, but I'd love to use it as a demo for when I get efpse script processing working.
Also, any type of game will be possible to make!
FPS will probably be the most common genre at the start, because it will likely be the only genre with dedicated tools in version 1.0, but there'll be more genre-specific templates/tools coming later, and the scripting engine will be advanced enough to allow anyone to build anything, regardless of what tools are included.
