A game whose life cycle is starting to wane. It's still debatable whether or not this is still one of the best FPS (if not games) ever released, but each update continues to eat away at what made it truly great. If you're not dying to random crits every 30 seconds, you're outright crashing. Valve would be better off just making a TF3 instead of persisting using technology that's been obsolete since a few months after its launch.

All the Minecraft without the 3rd dimension. Oddly, this kind of game works better in a 2D environment than in 3D, imo. A true testament of a game proving that graphics DO NOT a good game make.
