i guess they will look somewhat different in the past feature, but not much. they also wont effect gameplay, my guess is that they will be tucked away and hard to find like in halo 3
i love these ideas, but 24 players is the max an xbox can handle. and for AI in forge, i doubt thats going to happen. AI need nodes to work and i doubt forge would be that complex.
You should be able to. They aren't changing anything about the game except for graphics. And you can just press 'back' to find the skull if it isn't there.
