If you are in the same boat Proteus and I find ourselves in concerning Portal 2, as in you don't own one of the best games of the year yet, then we're all in luck. Portal 2 has recently seen a price drop of $20 bucks making the game now $29.99 through Steam. We meant to do the whole pre-order thing but kinda forgot and same thing happened during Steam's Summer Sale when it was nearly 50% off, but now we can make up for it any time with this recent price drop. We're having to be gamers on a budget here with that whole pesky home ownership stuff, but it's a worthy trade off. For your convenience here's a handy link to Portal 2 on Steam if you are interested in purchasing it.
