Yes Timberwolf, I own a Gamecube. All the Mk games, Deadly alliance, Deception and Shaolin monks had Gamecube releases, though due to the slightly more irritating story mode in deception I haven't personally bought the game. Soul calibur 2 was also released for the Gamecube, though (to my everlasting annoyence), Soul calibur 3 wasn't.
The main reason I bought the Gamecube in the first place though, was for the Gba player, so that I could play any gameboy, gameboy colour or Gameboy advanced game on it (I have a fairly extensive Gba collection).
also, as a retro freak, I deffinately enjoy the various retro collections out for the gamecube as well.
shin goenitz, that's quite a beat em up collection you have there. But not to be outdone, here's all the 1 on 1 beat em ups I own.

I also own a good many side scrolling beat em ups like Streets of rage as wel, but I won't list them here. I've also recently acquired a copy of Mame, but owing to my general awfullness at playing beat em ups on keyboards, haven't yet emulated many of them.
As I said, a Ps2 is probably going to be my next console, principley for Soul Calibur 3 and the like.
While I've played quite a few of the Tekken games (my brother is a big fan), I just personally don't like the hole atmosphere and mechanics of the game series, and the plot doesn't interest me too much, so I've never really bought many of them. I would however be interested in getting hold of the dead or alive games, sinse I've played them in arcades and their cool!
Now, I'd better finish this slightly boastful post before my head explodes.
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
