Gaming problem

Hi i'm stuart and i have a gaming problem now it's not the kind where i can't stop playing videogames but it is the one where i have nothing to play and next week i'll have a bit of money and thats where the problem lies.
I have'nt a clue what to buy, released this week was Forza 2 and while i knmow lots of people are going to say this is a fantastic game and that alot of people on my friends list will be playing it after the BETA of Halo 3 ends however i'm not a fan of racing games so should i jump onto the bandwagon and follow everybody on my friends list or do i just go out and buy something else, again the problem comes back because then it boils down to what the hell do i buy.

I could go with buying a few games that nobody has and rack up my gamerscore or i could just bit the bullet and buy Forza 2, now i don't have that much of a problem when it comes to the Wii as there is a game that i want for it and with the DS i'll just pick up something simple to pass the time.

So if there is anybody reading this blog (and by the looks of it there is very few of you) do i buy Forza 2 and follow everybody or do i just buy something else, if it's something else what the hell do i buy.
