Deutsche Computerspiele?

I seldomly play games, but I really loved playing Braid, Word of Goo, and Machinerium.

I also really love learning German. I've been gradually stepping up my consumption of German media, from Sesamstraße and Kleiner Roter Traktor to Raumpatrouille.

Does anyone have any German language games to recommend? Maybe an RPG or something where text plays a role?

Other language-learning recommendations would be welcome, too.

Thanks!
