Just got this game as a belated Christmas gift. Spent about 30 minutes or so getting the Homebrew Channel and Gecko on my SD card and started playing some TvC. The game is very cool and anyone who digs any of the older vs. games will enjoy it. I absolutely must pick up some classic controls now though. If you use the normal wiimote + nunchuk, all of the attacks are merged into the "a" button and specials are done with the "b" button, ala Smash Bros. That simply won't work for me, but might be a lot easier for non-vs. game players.
More as I play.
