Empire Total War
Diablo III
Starcraft II
Battlefield Heroes
Seriously, don't bet on Diablo III, the first two Diablos were mature-rated.
New one: Castlevania Judgement. It's a Wii fighting spin-off of a series that I have (stubbornly) YET TO PLAY ANY GAME FROM!!!
Oh well. I might get Aria of Sorrow and/or Dawn of Sorrow any time though. Probably gonna end up with Metroid Fusion first though, since I used to have it.
Frankly enough, I'm waiting to see whether Castlevania Judgement will do well. It doesn't look like it at the moment.
My new list.
Starcraft II
Command and Conquer Red Alert 3
Empire: Total War (Still yet to play a Total War game)
Paper Mario DS (Or you could just get the Paper Mario 64 in its original form on the Virtual Console)
Chrono Trigger DS (whose idea was it not to remake this game earlier!!!)
Castlevania: Judgement
Castlevania: Order of Ecclesia (what system is this for???)
Sonic Unleashed (still have faith in that blue hedgehog, mind you!)
Sonic Chronicles: The Dark Brotherhood (Time for the "other" platforming staple in the industry to get his own RPG!)
Would have had Final Fantasy Tactics Advance 2 here, but it's already out.
Next thing you know, I'm going to be playing A Link to the Past (GBA) and Wind Waker (need to get that since prices are rising quickly!)
