The Endless Dungeons

The Endless Dungeons is new graphical Roguelike consisting of 8 character classes, hundreds of monster types, and 99 randomly generated dungeon levels. You must level your character from 1 to 99, collect items and equipment to make him or her more powerful, and finally confront the boss of the game, Xantos, on the 99th floor of the dungeon.

This game differs from a lot of other roguelikes in that it's largely GUI- and menu based (similar to old console RPGs) and has turn-based battles.
