I've been waiting so long for this. The coolest thing is the FF and TF2 beta come out a day after my b-day (what a present)!
I've mostly been looking forward to FF, but some of the latest TF2 game play videos have really caught my attention. The graphics in TF2 are just insane. I read in one of the dev notes awhile ago that TF2 can use up to 700+ mb of video memory on the highest settings?! Hopfully someone will buy me a new computer for my birthday. This laptop won't even load HL2 ;D
