I just picked this up along with Pokemon Platinum earlier today and so far I'm liking it. Chapter 2 is having me a bit concerned now though but I think I'll be able to manage. Any other faults any of you ran across?
I had to ask myself the same question and it came down to PC simply because of the free content, the user generated maps and mods (the mall from Dawn of the Dead for one), and generally nicer player base won it for me.
