As much as I'm kicking myself over getting a Wii over 360, Endless Ocean made it all worth it. I wish you could do international dives though.

Endless Ocean 2 is a day one, full price if necessary, purchase for me. My Wii game of 2010 probably.
edit: I plan on posting pics of my collection as soon as I get it all cased.
GBA: Half done, need cases
DS: Done
Wii: Need Link's Crossbow Training cover and probably a better WiiSports one
PS2: Done
XBOX: Need a cover for my pirated Halo and probably some replacement cases for some used games (What makes Halo so great? I'd rather have my blank DVD back)
GameCube: Done, may get a seperate cover for Pac-Man World 2
PS1: Needs LOTS of work. Some games don't even have covers made for them.

N64: Half done, need covers
PC: Want to replace my Orange Box STACKpak with a dual disc DVD case, need covers for my very obscure PC games (Pajama Sam, RollerCoaster Tycoon, etc.

)
GB/GBC: Need to get cases, mod them. Already have covers.
I want my basement clean (and thus clean enough for pics) by June, and I want my fully cased collection along with it. Here's hoping.
