Dota 2

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.

It's a spectator sport platform with its own item-betting scene; it's a hobby; it's a profession, and a way to make a living. It isn't perfect and likely never will be, as each update tends to fix bugs and introduce new ones, and the tutorial could certainly use some work. However, with zero cost to play and one of the highest skill ceilings of any game I've ever encountered, Dota 2 is a modern multiplayer masterpiece.

The original Dota was an unexpectedly powerful blend of clashing genres and disparate elements that ended up taking over the world, and Valve's successor retains the original rules and characters while adding in a cheery free-to-play model and slick production values. The experience of playing Dota changes day by day--some evenings will be exhilarating, while others will kick your morale to the curb--but there are few games as worthy of your time investment as this. Those who choose to commit to Dota 2 will find many happy hours within this immaculate update.
