Dwarf Fortress.
Id also recommend Nethack. Hours of fun for the whole family. Its easy enough to understand visually without a tileset.
In terms of shooters there's Urban Terror, a more realistic shooter using the Quake engine, Open Arena, which is basically quake, and Nexuiz. I haven't played Nexuiz or Open Arena much, but Urban Terror is quite fun once you get the hang of it.
