Its a really good idea! But only if You have a team with 4-5 Guys.. Just think about it, FPS Creator with almost the same speed as the Halflife 2 engine! The animations wourld be soooo mutch faster! The FPS Creator wourld be converted from a toy to a professional tool! Soon or later this will happend. (Someone will do it.)
Another intresting thing is that V6 of DBP will be mutch faster than previous versions. (This is what I have heard I am not sure!)
If this is true We dont need to convert it... We just have to wait for FPSC V2...
Trust everyone...
