StarCraft II

Starcraft II came out in 3 parts, each covering one of the games asymmetrical factions.

Single player is pretty much as you would imagine except, before missions, they added the ability to change between unit variants and abilities. The story is as you would expect from Blizzard, bearable, can't say much without giving any spoilers but I can say that it's the games weakest part.

Blizzard does a lot of stuff to encourage people to get into the multiplayer, which is arguably the core of the game. As it stands right now, the multiplayer is pretty balanced, but to be even remotely good you'll have to put in an ungodly amount of work, which might turn off a lot of people.
