Loving the Cave Johnston stuff, he's almost as awesome as GLaDOS! And I'm no too concerned about the game being short, it's one of those games that's still fun when you replay. I think I've beaten the first one 4 times. Portal was the only reason I even bought Orange Box. Played it and a little HL2, haven't touched the other 3 games on there. I should do the HL games at least....

I hadn't ever played Portal until 4 days ago, and now I'm addicted. I'd read the rave reviews for P2, and remembered that I bought a bundle pack a while back on Steam that included Portal. I broke that out and played it and was left wanting more. The campaign for P1 only took me 2 hours, and the advanced maps and challenges only a couple more hours. Now I've got Portal 2 downloading through Steam.. The wait is murder, and the cake is a lie!
is there split screen co op on the PS3/360 versions>
Finished the XBox 360 version the other day and it's an early contender for Game of the Year imo. Stephen Merchant was hilarious and it's great to play a game that actually challenges you to think for a change! Superb stuff.
