Dragonball Z Budokai HD Collection - Includes HD versions of DBZ Budokai 1 and 3. Budokai 1 had the best story mode out of any DBZ game ever, and I never got the chance to play Budokai 3 back when it first came out, so that should be fun.
Kirby's Dream Collection - Compilation of Kirby's Dream Land 1-3, Kirby's Adventure, Kirby Super Star, and Kirby 64. I've played most of these already, but it might be nice to have them all on one convenient Wii disc.
...and most importantly,
Nights into Dreams - I never had the chance to play this one since I never owned a Sega Saturn, but I've always wanted to. Now I get to play it in HD on the PS3. I can't wait.
Other recently announced games I'm looking forward to include Tales of Xilla (a North American release was finally announced) and Naruto Ultimate Ninja Storm 3. Hopefully we'll get even more good video game news out of San Diego Comic-con this weekend.
