Mass Effect 3 w/ texture mods (4096 maps) - got the trilogy for $10 on GameStop.
Also been playing a LOT of the ME3 coop - I really like it. The Geth Trooper is insane with the flame thrower - melts all armored targets in seconds. I was able to go from not having played the game at all to doing Gold matches in a couple of days. Other characters I’m not nearly as good with.
