Cool, I've tried FPS Creator, it has a lot of bugs (well it did for me), but I made a couple decent things with it
Although, I much prefer Sandbox, much less buggy, I can make large size maps WITHOUT it lagging (like it does in FPSC, on a small-average size map

), things look better in my opinion, there is more I can do!
FPSC is good if you want guns in your game without scripting, and easily (as that's important for an *FPS* Creator

)
