The lights are on
Whether it's Half-Life's well-polished single-player experience, Left 4 Dead's intense multiplayer mayhem, or the amusing puzzle-like experience that was Portal, it's hard to argue with Valve pedigree, but you can certainly try if you'd like.
I logged on to my Steam account earlier today and saw a new update. In one of the adds it sayed that in celebration of Steam comming to Mac, they are going to be giving out free downloads of portal. At first i didnt believe it but then i downloaded it and it was completely free!!!! If you dont already own it and you have a steam account, i advise you get it. The give away ends May 24.
My friend downloaded it and we have been playing it several times through!
