Best Custom Stories?

[nofsky]

As far as keeping the same, or close to the same quality as Frictional Game's stories there unfortunately aren't many custom stories that do (I haven't played them all though). Through the Portal is great, and I liked Isle as well. A lot of unreleased projects look really promising though, it takes a while for people to get familiar with the tools, scripting etc. so I think we'll see some really good stories in the future.
