Dungeon Crawl Stone Soup is roguelike rpg game. So it has randomly generated dungeons and it is also extremely difficult. Mostly due to the hunger system and the fact that your savegame is permanently deleted when you die. But I'm sure someone likes to play these kinds of games. There is an ingame tutorial where you play as a premade character and get extra hints. Most roguelike games usually only have ascii graphics but this also has a tile based mode. You can use the keyboard or mouse. When you die you lose your save but this does give a much greater feeling of accomplishment when you succeed.
Dungeon Crawl Stone Soup is a fun, free rogue-like game of exploration and treasure-hunting in dungeons filled with dangerous and unfriendly monsters in a quest for the mystifyingly fabulous Orb of Zot.Dungeon Crawl Stone Soup is a variant of Linley's Dungeon Crawl that's openly developed and invites participation from the Crawl community.
Dungeon Crawl has superb, deep tactical gameplay, innovative magic and religion systems, and a grand variety of monsters to fight. Crawl is also one of the hardest roguelikes to beat. When you finally beat the game and write your victory post on rec.games.roguelike.misc, you know you've achieved something.
