Hi I have a base model 13" MacBook Pro which I bought in Sept 2009. TF2 is available for $9.99 right now for Halloween and I am thinking of buying it. 1. I am concerned about performance. How will it run on my MBP? I only have 2 GB RAM, a 2.26 Ghz C2D and 9400M. 2. Is the game still actively played and not deserted like some older online games? 3. Are the other players mostly addicted nutjobs with no life who will finish you before you can know whats going on? Or as a beginner will I have a chance to play the game properly while enjoying it? 4. Is the game a good one for someone who just wants to play it casually once in a while? Thanks.
