My friend and I both went to pick up this game, and we had great difficulty finding a Gamecube copy. When we finally DID track one down, my buddy bought it (I figured I could find one later for cheaper), but after he did, I asked the checker why it was so hard to find--well, apparently its been discontinued by Sega, and they are pulling the ones that haven't sold off of shelves. Why they are doing this I don't know, but it is my personal speculation that maybe there are some licensing or copyright issues?
A quick check on ebay confirms this, as copies are selling between $80-100. FOR A SPORTS GAME.
This all elicits one big, resounding "DOH" from myself.
So if you happen to find a copy, pick it up, and if you're super nice, maybe send it my way? Nobody here likes sports games anyways, right?
