Since a VIP map system is possible, who's up for a trip way back into some of the near-baby days of counter-strike to re-discover "escape" maps.
The simple concept of escape maps were that the terrorists were suppose to escape from what is now a "hot" zone. while the CT's hunted them down.
I'll have to look up exact specifics about the gameplay style, but there are some way old-school CS-ers who miss this gameplay style, and while I was never around for it's mainstream, it could become popular again, if the maps are made right.
Just another idea for a project for people!
