Portal is available for free on Steam from now until May 24. I just finished and the last level was awesome. GLaDOS is a trip. /img/vbsmilies/htf/biggrin.gif
I think I may be buying my first PS3 game. I've had one simply for the blu-ray player because most of my friends have 360's so if I wanted to play online, it made sense to get the 360 version. But, with this, I'll like the convenience to play on my computer too.
