I purchased Portal 2 the same day as MK. I won't go into it too much but the game is Valve 101 which is to say its funny, endearing, intelligent, challenging, interesting, different, atmospheric, brilliantly designed and brilliantly written. GLADOS is the most ingenious character since System Shocks SHODAN. The way she toys with you is something I have rarely experienced in this medium i.e.commenting on how fat you look, the fact that Chell's parents abandoned her at birth before informing her that its in fact her birthday. The bitterness in her voice is almost frightening and its serves to add a bit of tension to the proceeding which the first game lacked. The main reason I love this game is that it does something that the first game also did extremely well. It places you in an environment and its up to you to make sense of it all. There are no paragraphs in the manual that succinctly explain the inner workings of Aperture or the origins of the company as a whole, it is solely up to the player to glean what they can by looking around their environment, listening to what characters say and the way they say it. I haven't finished the game but I hear the ending has lead to a lot of discuassion so I need to get there.

Briefly I have also been playing God Of War HD during the PSN downtime. That game is great obviously. Nothing much more needs to be said.
