I've not bought Portal 2 yet. A couple of reasons for this - twin boys that came along last November taking up most of spare time & a PC that locks-up everytime I try to play the only game I currently have installed, TF2 (dodgy gfx card I think). I notice the forums are full of the usual talk of completeing the game 5 minutes after it was released! Can I take this as meaning it's not the longest game (again) in the World or do people just have much, much more time on their hands than I do?! I'm looking to build a new PC at the end of the Summer so I doubt I'll get to play Portal 2 until then ...... by which time Valve will probably be almost giving it away! Will it be worth the wait for me?
