None. I've never managed to play all the games I want on the console + handheld I own (N64 + GBC, GC + GBA, Wii + DS).
Throughout each year, there are at least 10 titles I really want. Do I buy 10 titles before christmas? Not really, more ala 7. Then there's between 3-4 and 10 titles that I still really want left that I can buy for christmas.
This year? Not at all.
Wii Music - seems awesome. Might give it a shot, but I have a hearing problem and have almost no sense of music, so that could be a problem.
Okami - Zelda copy? Perfect!
Super Paper Mario - Never liked any Mario RPG/Platformer before SMG, and this one seems a bit short (a mere 15 hours), so maybe not. Would have bought it if it wasn't for competition.
Batallion Wars - I love FE's, and most of Intelligent System's works. Seems a bit short though, so might not get it. Still, very cheap now.
Fire Emblem DS - I've already played FE1 (with the exception of 5 chapters, I played FE3, which only has 20 of the 25). Might get it though.
And I could consider
de Blob
Sonic Unleashed
But I don't really know, as I mentioned earlier - SMG is the 1st platformer I've ever really liked (BK was good though).
