Just wondering if, after the contest is over, I would be able to turn my entry into a CTF map?
Yeah, why not. The rules are you don't have to put your vmf out for others to use.
I'm gonna turn mine into a 5 point anyway 'cause I haven't made one yet, but ctf's need a good balanced mid too.
I actually think I'll probably do an arena version too since it'll basically be done by then.
