@hans_maulwurf: Saboteur was such a great game. I understood some of the criticism but I loved the world they created and the black and white aesthetic was stunning when you first start the game.
While it's a hard game to go back to after Diablo 3 and Torchlight 2 came out I still really like Sacred 2. It's janky, buggy, and has one of the worst cameras I've ever experienced but the massive world and loot grind are incredibly satisfying.
If PC and IOS games count I would also recommend SpaceChem. This is one of the most challenging and rewarding puzzle games I've ever played and any fan of the genre should check it out.
