Dungeon Crawl Stone Soup

DCSS did not spawn a wave of many clones and variants, as happened with other major traditional roguelikes, Angband and NetHack. So Dungeon Crawl remains pretty special and unique product. Nevertheless, it has much in common with other games in the genre. Deep skill leveling system, the decent set of races and classes, persistent dungeon levels, and the most special thing about DCSS — gods who can be gracious or wrathful depending on what the player does. Superlative replay value. For those who new to roguelikes, DCSS has a tutorial, a special mode with hints and handy UI with graphical tiles and full mouse control.
