Well that’s a good question there….
I you do (or used to) play guitar then you HAVE to try this game. The motions are as close an approximation of the real thing as it can be without making it unduly frustrating to non-guitar players.
When I first saw the game I thought the same thing, then I tried it and was surprised at how much fun it was. Maybe you will be too.
I’m just glad we didn’t use the same logic when GTA came out or we’d all be in jail for murder and whatnot.
