I now see why they're not letting us make our own maps for it: they want to keep releasing their own, in the hope that it keeps the game alive as long as possible.
As said, napalm. I wonder how will they handle the burning, and will you be able to set buildings alight?
On another note, I see that the xbox users will have a new mode that will allow them to play co-op against AI. Although this is of no interest to the PC players, the fact that said missions could be played at different times of the day is.
If they combined the time of day to BC2:V, then lighting the huts on fire in an evening setting would be a good laugh.
In saying that, I wonder how they could make some of the urban building intensive maps, or should I say: how many buildings will the servers be able to handle? At the moment, there's usually a maximum amount of buildings that can be taken down (and some, that can't, like in Port Valdez), so I can't see many of the urban maps being migrated.
