Great for all you bhopping elitists out there, you know who you are.

Succumb to the hype.

Excellent episodic story, where your choices will indeed impact your experience.

"Old, but gold." -if you know how to mod it.

The whole Half-Life series is a must-have.

This may be vastly unfinished, but it's packed with amazing graphics and awesome gameplay, check it out, it's in Alpha.

Well.. it's Garry's Mod, end of discussion.

This game is like no other. It's good, but not too good. It's "smooth" and perfected. Give it a chance.
