Music Games I own

Admittedly, when the first Guitar Hero came out, we thought it seemed like a pretty cheesy getup.  We had actually gotten the game for a friend of ours for Christmas.  He came over, opened it up, and decided to plug it in.  We actually thought it was pretty cool.  The friend left his copy at our place since his PS2 was busted, and we ended up playing the crap out of that first Guitar Hero game.  We'd basically been hooked ever since.  I only wish that they hadn't released so many games within a relatively short time span. 
 
I probably don't even want to consider how much money was spent on these games, and on all the DLC we have for them.
