Alan, you give us far too much credit. Do you really expect us to start creating maps and not playing your game?
But in all seriousness, it will probably take us a bit to get used to the changes made in the custom KF2 editor. The spawning volumes, lightmass issues, and pathnode chages are my current battles.
Also, would like to see what other map ideas you guys have before I start working with fellow mapmakers/modelers on the ideas that we (the community) have.
The only one I will do definitely is the Paris catacombs. If you guys are doing a version also, I wonder how much different it will be from mine. I plan on mine being brutally difficult.
