That's the best good news/bad news I read in a while. Don't feel bad, you took the mantle and did a lot for the EFPS community already, and this looks pretty amazing. I just hope it will be as accessible for us programmatically-challenged people as EFPS is. Just take it easy, take your time, there's no rush, no pressure. Good luck!
Thanks!
The built-in game genre templates will allow you to build games in the engine without writing any code, very similarly to efpse.
You'll also be able to adjust script values/settings from within the editor, so you'll have a bit more control over how each weapon/enemy/whatever works without ever needing to look at the code.
