You guys also have to realize that with the exception of water maps, crysis has very abrupt map boarders.
Alot of the terrain will need to be made in-accessable to all units to provide for terrain that looks realistic and doesn't cut-off on the map edge.
For instance in my 2048x2048 map I am making for Crysis singleplayer, only about 1/10th of the map the player actually plays in. The rest of the map space is for distant terrain (as it's a desert map on terrain). Then again this is only an issue for me because deserts tend to be flat, and when your gameplay takes place ontop of a mesa, you can see REALLY far in the distance.
Currently the issue for me though is making the edges of the map not visible yet still finishing my map intime for the ICMC competition. I might end up not having enough time to get a proper boarder that looks realistic in my map simply due to time alone. If I didn't redesign my map half-way though the development this wouldn't of been an issue of course

What can I say, I was a newbie then at really coming up with a solid design that didn't just involve whatever was on my head at the time
