Rogue Empire is a Rogue game which also run natively in Linux. It's one of the better rogue game out there and can be obtain on Steam for a reasonable price.
There are 8 races and 7 class' if you also get the DLC package. Though the graphic may not be top of the notch, it has its charm. There's plenty of opportunities in the game and the skill/magic combination is vast.
