The Dark Spire for DS... it's a REALLY FRACKIN' HARD rpg, one of those original dungeon crawler rpgs. But I love it :D Even if it is nearly impossible to beat

Lost Planet (Xbox360) - Third person sci-fi shooter. Really cool
Kingdom Under Fire: Circle of Doom (Xbox360) - ActionRPG but it gets kinda boring after awhile. I'm still determined to beat it though!
