Thanks Guys, I went ahead and grabbed them both. I figured showing support was the most important thing, so more games like this can be ported in the future.
I loved portal, and it's probably one of my top 10 all time games for sure. A really great experience. I enjoyed Portal 2, but I liked the original more, mainly because it was the introduction, and a lot of what made portal unique and special, became a been there, done that in the sequel. I did enjoy P2, just not as much as the first.
In regards to HL2, I've never been a FPS fan in general, but this seems worth a romp. The only FPS I've ever liked are the Metroid Prime series and the first Bioshock. These games weren't typical of the standard run & gun standard FPS fare. I'm gonna try to invest some time this week in HL2, and see how it goes early on. So time will tell how I feel overall.
