1. the reality of the game, I love how all of the things in it are real and used in combat. If you have a good team you can use strategy to win and work together. also the game is just awsome, it is fun to play ....it is an addiction.
2. it will be in my xbox untill they make a new one.
3. maybe, it depends on how the game ends, if not they might make a cousin game to it. I am guessing they will leave an opening or make one with a different plot and no relation to this one.
