First of all, my roommates and I finally got an HDTV. We've been waiting for a good size that was about $300, and it finally happened.
So we got component cables for the DVD player (only $11) and a universal Wii/Playstation/Xbox cable set ($20, great deal, considering the Wii-only cables I could find cost either $27 or $35).
As for games, I got Crystal Bearers (perhaps my first first-day purchase), The Conduit, Dragon Quest IV remake (all three for myself), Wii Music (my roommate wanted the game, and now it's only $20), We Cheer and Mario Tennis Wii port (for another roommate), and The Last Remnant (for my brother).
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
Plus, just for the hell of it: Kelly Brook at the 2008 BAFTAs
