I'm on the last level of Halo, but I'm going to finish it tomorrow (I have the day off of work tomorrow). I'm waiting until my next paycheck to buy any more games.
Welcome to the fold Morgan. I just recently purchases a XBox myself and I enjoy it greatly. Good games to get are Buffy, Mech Assult (renting it, but love it), Knights, Unreal Champship, and Serious Sam. Enjoy playing it in Scooterplex.
I'm most likely going to skip out on a lot of the earlier games, simply to save myself time and money.
I just got KotOR today and have played it for over 3 hours so far. It's good in many ways and bad in a few, but overall I'm digging it. Can't wait to try it out in the Scootplex.
