Virtua Figher 2, published by Sega is a by the book beat-em-up game and therefore only playable for 2 players at the same time. If so, you can only play tournaments on LAN. In any case the key assignment is “fun” and after a certain time the wrists don't feel unchallenged.
It's hard to believe, but this ancient game is still available at Steam. However, two characters and a game mode seem to be missing.
There doesn't seem to ba a patch or a crack for the game. So you have to insert the CD or mount an image.
