If you buy and play SimCity before March 26th EA will give you a free game due to the recent troubles on the SimCity servers. Even though there are only minor server issues left for them to deal with they are still giving you a free game.
The games you can choose from are:
Battlefield 3 (Standard Edition)
Bejeweled 3
Dead Space 3 (Standard Edition)
Mass Effect 3 (Standard Edition)
MOHW (Standard Edition)
NFS Most Wanted (Standard Edition)
Plants vs. Zombies
SimCity 4 Deluxe Edition
The choice is much better than I expected it to be. Dead Space 3 only came out last month!
