Pretty fun game. Can't play online yet because I don't have an Xbox Live Gold membership.
It seems like something I'd want to do.
So..... I also bought a 3 month gold subscription card, yet I found out that this weekend is free xbox live gold gameplay weekend. I'm still debating on whether or not to activate the card now or wait till the weekend and have that couple extra days of playtime.
But alas, while writing this I came to a solution.
I made a new xbox live account, which gives me 1 month of free gold membership.
So I guess I can just play on that until this weekend, and earn the achievements and etc. on my main account then.
I know I'm not the only achievement whore :D
