Looking for Coop Games and a small GA

Hello,
here i have something for you:)

At the moment i am looking for some good coop games(not local coop). We played Hero Siege
which is really good but the Multiplayer needs some work until its really good to play^^ Maybe someone has some ideas for similar games like that?:)

Edit:
We played already: Torchlight1+2 / Hammerwatch / Terraria / Trine / Portal / Magicka
I dont like FPS games^^
Forced i will buy today :) - bought^^ If someone is interested in that game too you can get it on Bundlestars for 2,09 Euros at the moment.
