Firstly my opinion on PORTaL 2 is that is diserved beter than the 9 that it got but still I am satified with another great ValvE game. What I was going to say was that PORTaL 2 should get re-reveiwed once the (FREE!!!) DLC comes this summer that will include one of the only two bad things about this game which are challenge maps (and just more maps in general). Thank you ValvE for making another amazing game.
