You might want to decide on a gametype and layout before doing any detailing. If you need to change something, detailing usually gets in the way and is annoying to work with, layout-wise.
Sure, that's good practice, but what if your layout turns out to be bad? If you change it, a lot of detailing will go to waste!
Get started on the artpass man. If you really enjoy detailing (as do I) this is your type of contest. http://artpass.tf2maps.net/
Yea I wanted to get in on it but I didn't read about it till like a few days ago and decided it wasn't enough time.
Do you think KOTH would be the only gamemode feasible with out VERY distinguishable difference between red and blue styles? or say CTF with several blue signs and red signs be good enough?
