Let's see, I'm catching up on all those years I left console gaming, so disgusted I was.
So I'm playing old GC games and Wii games on the Wii (still have my GC though) : Tales of Symphonia (huge game, put me back on loving Action RPG), Zelda WW, Skies of Arcadia, Zelda TP. Some games I started but I probably won't finish, or not this year : MGS (the one on GC, not my type of game), Metroid Prime (will finish this one, later ...).
I love to do and have everything in a RPG, so I often score 150+ hours in every (good) one. Given the few hours I can play a day (often 1h30 max, a bit more at week end), these games can last me 1 full year, if not 2. I surely won't have finished them all when FE akatsuki no megami hits Europe, and then, the FE game will take priority.
On the DS, I have one GBA game I will restart to finish completely : Final Fantasy Tactics Advance (this one is huge too, shoudl score 200+ hours on this game, which I'm playing only when commuting).
I'm also playing NSMB, Advance Wars DS (I prefer FE from the same developers), Tennis no oujisama crystal drive.
