it's painful how badly i want to play rock band

Specifally, the Beatles Rock Band. Despite having never played any Rock Band or Guitar Hero game in my life, or, for that matter, any Xbox 360 games. Yeah. And yet, here I am on Amazon, looking at the game and thinking, oh, my, god. The value pack is 130 dollars while the Limited Edition is like 230 but still. 130. Well I don't actually have an xbox. It's my dad's. BUT I WANT TO PLAY THIS GAME. I'm not even a gamer. Ah god. This is painful. I could ask for it for my birthday but here's the thing: if I am getting anything for my birthday, it's going to be a digital camera, the Beatles Remastered CDs, or the Beatles Rock Band. I'm sort of leaning towards the CDs but ROCK BAND for god's sake. Then again,I wouldn't get to play it most of the time, cos it's my dad's xbox, arghh...
