No, that's not a particularly astounding deal. SSBM is a Greatest Hits game, so it runs about 30 bucks brand new. AC still goes for about 50 bucks, and the Gamecube is 100. The Zelda Collector's Disc is badass, but it's free with the Cube purchase. Add tax and you've got about 184 bucks. You didn't lose money on it, but you didn't save any either. You paid basically exactly what you would have if you had bought it from Wal Mart.

Here is my universal list of must-own games for new Cube owners.

Metroid Prime
Eternal Darkness: Sanity's Requiem
The Legend of Zelda: The Wind Waker
Super Mario Sunshine
Star Fox Adventures

Mario Golf: Toadstool Tour

3rd Party Titles

Resident Evil
Resident Evil Zero
Viewtiful Joe
Star Wars, Rogue Squadron 2: Rogue Leader
Skies of Arcadia Legends
Metal Arms: A Glitch In The System
Beyond Good & Evil (Don't have it yet, but I've heard nothing but positive things.)
Super Monkey Ball

Ask me about any one of those games, or about any genre of game that you're particularly interested in, and I'll give you further information or recommendations on games you might want to take a look at.
