Only limited to your imagination I guess, good games, not hard to create levels, but theres not enough help available.

Been trying to play this game for ages, can make a nice little game, but theres slight problems like how to put a door into a wall, just little things like that and it's annoying that theres no help available! Consulting the manual isn't helpful and as of yet I can't get much support online, excluding the FPS-Creators official forum, although they haven't been any help yet.
So really if your looking to get this product, you may have to put some effort in, the learning curve may be a bit steep. By all in all it's fun and you can make countless games as long as you have the patience.
