It does start off slow, the first hour or so is just an introduction to the game.???? all my steam friends are already playing portal. they said it starts off slow. you can buy it on on steam.
well it did come out yesterday, so yeah, you can buy it and all the other games offered in orange box off of steam individually, at a higher cost of course.
You know you can buy it and download it from Steam directly right?Just bought it after looking in 4 stores. Bestbuy, Circuit City, Gamestop, and Target were all sold out. Eventually found it at Wal-Mart.
Portal is amazingly fun, TF2 is a good time, and HL2: Episode 1 and 2 I haven't played yet.
