I was wondering how much the Escapist community has tried out any of the Portal 1/2 user-generated content, and what their favorites were. If you're not aware, Portal--like all Valve games-- is designed to allow users to generate their own content and has a very active community [http://www.thinkingwithportals.com]. Obviously, they're not as polished as a huge team of paid professionals could make, but I'd say if you like Portal they're definitely worth playing.
Portal 1: Portal Pro [http://www.moddb.com/mods/portal-pro] and Rexaura [http://www.moddb.com/mods/rexaura] are two of the most popular and highly-related mods. I can't recommend them enough for anybody who thought the original games were too easy. Rexaura even got reviewed on Rock Paper Shotgun [http://www.rockpapershotgun.com/2012/01/27/moretal-portal-mod-rexaura/] recently, where it was called "utterly delightful, probably the best chunk of non-Valve Portal modding I've played."

Portal 2: Most of the currently generated content is being made for Portal 2, with tons of maps coming out every week. 12 Angry Tests [http://forums.thinkingwithportals.com/downloads.php?view=detail&df_id=1441] is probably the best map pack from recent memory. Other great Portal 2 maps/map packs can be found in the Community Spotlight [http://forums.thinkingwithportals.com/downloads.php?cat=14] section of the thinkingwithportals site.
