Dota 2

And this dichotomy is perhaps the best descriptor I can attach to Dota 2. It is frequently a game which occupies two opposite spaces simultaneously. It is the best game. It is also the worst game. No game has ever made me as miserable as Dota 2 has. But no game has made me feel so consistently rewarded for my time, and as consistently, wonderfully connected to the friends I play it with.

A great PvP game that offers some of the most intriguing and nuanced team combat around. As with all multiplayer games, sometimes the enjoyment can be marred by less considerate players, but when everyone is giving it their all, DOTA 2 is intense, challenging, and hugely enjoyable.
