As I discussed the Farcry map editor with my younger cousin, he kept asking if he could play, which gave us the idea for a Two Player Map Editor. I'm sure it would be no problem, seperate screens so that two people can make the map on their own, Player one has total control over some things, such as entering the game for testing (via back button!), where both players must be in the game at once, it would be an enormous problem to have one player editing the map, and another walking around in it! I know the farcry engine will not support editable maps while being played, it just makes sense, why bother making this possible if you never need to do it? Both players have a "my zone" which may be a space of air above the map and on the map that the other player cannot edit, you cannot imagine the possiblities if two people make a map together!
BTW I am a sort of old member of these forums, I just can't remember my old pass/name! My xbox was in for repairs for 3 weeks, I forgot all about farcry.
btw I know what is possible in a game and what is not, I am not some silly newbie who thinks graphics are just bad looking because the artists are lazy (:P)
