Though it may be occasionally bloated and low on display options to stop me from getting sick when i play it, the puzzles and inviting nature of the game keep me coming back albeit in short spurts.

Solid mechanics and controls make for an addictive game play experience during the first few hours, and then the game's superb story takes the reigns and drives you to the end.

Though I've played more hours than I can count on Gmod I can't say the game play really was the most compelling part of it, it's more of a glorified virtual playground for you and your friends.
