Let me get this out of the way first: I have an Xbox...love it, still my favorite! Anyway...my son has been after me for quite some time about getting a Gamecube. I figured that since he did so well in school this year, a Gamecube might make a nice "treat" for him. Soooo.... I picked up a black unit today for him, along with Sonic Adventures, as this was a game he really seemed to like. So far so good, it looks to be a really well built little unit (and I do mean little). My question to you guys is this: What are the "must haves" for the GC? I've heard about Rogue, SSBM, etc., but what really stands out as a game that every cube owner should have?
