Genuinley one of the best platformers I have ever played.

It's fun and stuff. So ye.

It's like a simple version of GMod, only lacking worldwide servers.

Valve compleately ignores the community and conitinues to produce updates that stray from the relaxing casual shooter it once was. Great meme though.

Aside from being a meme breading ground, you can truely do whatever you please rather that be simulating the holocost, building cars or troll.
