Super Crazy Guitar Maniac Deluxe 4, by Second Impact Games, is a fantastic music game for pc, the only free music game that I think can be compared to Guitar Hero.
This game is immediatly addictive, and I like it so much that i'd want to play a sequel.
I'm sure I'm not the only one who wants SCGMD5, and I hope 1000 signatures will make understand to Second Impact Games that lots of people share my same idea.
Thanks.
