so i don't know if you guys remember it, but a while back i made plr_rollout. (the plr map that plays like a TC map) it's fully lit, and fully playable. the thing is that it's still 90% dev textures due to time issues. so my question is: "is an untextured map still submittable?". - i know it'll probably get penalised because of lack of asthetics, but i did put quite a bit of work into it.
Some of the maps in the contest still have dev textures. So I think it would be fine for you to enter.
It depends on the judge but I know that I would vote for a fun map that is well put together with dev textures over a beautiful map that doesn't play as well.
