I just bought Guitar Hero 3 for the Playstation 3 but I use to own it on the Playstation 2. I love this game as it's really fun and will keep you comming back for more.
This game is one of those games that will take you a while to get good at. At first the game will probly make you mad as it takes a bit to get use to playing the guitar with out wondering where your fingers are located on it. Once you get the hang of the struming and where the frets are though you will fall in love with this game.
This game is great fun for the family as well as you can buy a second guitar and play against the other person or the two of you can work together and do a co-op career. This game also has online play wich is great as you can play against other people that own Guitar Hero 3 as well. There is also additional songs that you can download from the Sony store on the Playstation 3 or from the Market place on the Xbox 360.
