Well, this morning I beat Portal. Wow! Outstanding game! Technically I still have things to do. Right now I'm going back through it again in developer commentary mode. This basically makes you invulnerable and adds little commentary icons throughout the levels that you can activate to hear the developers tell you things about the game. It's a fun way to learn more about the design and creation of the game. After that, there are advanced and challenge versions of the levels to play through. I'm not sure exactly what those are like, but they're supposedly harder. We'll see.
I do think I'll need to play through the final sequence one more time so that MrsKheldar can get a chance to watch it as well.
All in all, this was (and as I continue to play in the different modes will continue to be) a great game, and well worth the money I spent.
