Game systems and video games

If u were to have 1 game system and 1 game what would they be? I like the 360 and halo 3 because u can create places and I like to talk to Aryton while we play on it. we play on a team and sometimes on a different team but when we are together in a team we do really good. Some people are good and some suck. Usually the sucky people are on my team and keep betraying me. The only reason i dont like halo is because of the campaign it is easy but u always have to do it again and again for achievements.
