I was really surprised how short Episode 1 was. The Zombines are a nasty bunch. The only gripe I have with Episode 2 (and Sorce gmes in general) if the ungodly amount of HD D space they take. EP2 takes the cake, since not only does it need it's own resource files, but it also needs EP1's shared files, plus the base Source files as well. Nearly 10 GBs worth, all in all. Does anyone else have a bug where the game slows down to a crawl after the Vortigaunts start bringing Alyx back and Freeman starts seeing things? You know, after getting the shining extract? P.S. Portal is still cute.
