I pre-ordered. That should be enough.
PS, to those who think pre-ordering is retarded, it's worth it in my town. The employees are all gamers and really nice. The guy usually in charge gave a me a copy of ME2, with the pre-order because there was a goof up. The computer had put in Dead Space 2, instead. He still gave it to me.
Only if EA made the activation process easier. It took me a bloody half hour to get that armor.
Also, there were exactly 4 copies of the game left when I bought it on release day. God was I happy i pre-ordered.
