I miss this game.  I want it again.  And I'm wondering, what's the best system to get it on.  I already know I don't want the version in Street Fighter Anthology on PS2, because it doesn't even have the characters added for the home version.  I'd consider the PS1 version, since the PS2 will play that.  I'm considering getting another Dreamcast, so that version's under consideration (is it me, or was the AI harder in that version?)  And how's the PSP version?  I don't have a PSP, but I've been considering it, and I know the PSP version has extra characters (I think there was a version on a Nintendo portable, either DS or GameBoy Advance, but I don't remember which.

If you're just after one of the original home versions then I recommend getting the PS1 game. It may not be the best looking or the fastest loading of the home ports, but it doesn't have the bugs of the Dreamcast version or the horrendous price tag of the Saturn version. Alpha 3 MAX on the PSP does have a couple of extra characters though they are nothing special. The GBA game is a very different experience because of the limited controls.
