I played through HL2, HL2Ep1, HL2Ep2, and Portal. I've messed around a bit on TF2, but I'm kind of all played out for now. Every game on the disc is awesome. In general, I'm pretty much tired of shooters, but once I started going on HL2, I didn't stop until I was through all of them. Episode 1 is the weakest section (but still fun) and Portal is a hidden gem. Portal's fun and weird and hilarious and a little creepy. And the end credits song is hilarious.
