I just reinstalled wow, but don't want to play anymore?

I just got a new gaming pc but i'm getting bored of wow, 5 90s and just waiting for wildstar to come out june 3, does anyone know some half decent games i should play till then. I have never played wither series or minecraft. People say great things but still unsure
any other suggestions would be great thanks

I hear The Witcher series is good but I haven't played yet.
I loved the Mass Effect series.
I liked Dragon Age: Origins Ultimate Edition though I haven't finished it yet.
Far Cry 3: Blood Dragon was amusing in a juvenile way, worth it on sale.
If you like fast paced zombie action try the Left 4 Dead series.
For slower paced zombie action you could give Project Zomboid a try. (It's Early Access though, not complete) - I have sunk a lot of hours into it though.
State of Decay wasn't bad at all, on sale at least.
A lot people like the Torchlight series. T2 has multiplayer.
The Portal series was quite amusing - I liked them a lot. Portal 2 has a co-op mode.
The Walking Dead has a good story - worth it on sale.

There's some ideas for you, at least - hard to say more, without knowing what you play and like.

EDIT: Oh, Dishonored was great.

The S.T.A.L.K.E.R series is pretty good, though I only finished Shadows of Chernobyl. My advice for that one: play with mods.
