Lately, I've been playing mostly Smash Bros. Brawl (almost exclusively multiplayer), Mario Kart Wii (mostly multiplayer, I'm also trying to unlock everything on my Wii) and Civilization 3 (I have Civ4, but my laptop needs to be fixed and it won't run on this computer...).
I haven't been playing any one-player adventure type game in a while. I beat Twilight Princess, Super Mario Galaxy (I could still do it on Luigi mode, I suppose), Metroid Prime 3, Chrono Trigger DS and then there hasn't really been anything that piqued my interest since then.
But you know if there's another Zelda, Metroid, Mario or Chrono game, I'll jump right on that shit. I might also be tempted by a quality Mega Man game (speaking of, I still haven't beaten Mega Man 9... Dr. Wily's castle is so hard
)
