Just saw the arcade flier up on TAFA, and was reminded of the great times I had with the DC port of this back in the day. Easily among my Top 10 3D fighters ever. I guess you could call it the Smash Bros. of 3D fighters, and that would be a fair description.
Too bad the sequel sucked... :(
I have the PSP collection port somewhere, which I think is supposed to have some extras. I'll check it out at some point and report back with some impressions.
