this game randomly generates a dungeon for the player to explore having a lot more options and encounters than other games of its time or even now lack at times. Its 2nd edition rule set but for a dungeon crawl game i give it high marks. (note: in second edition some races could not advance as high as levels as humans to give humans an edge since they lacked resistances and ability bonuses of other classes so needs to be warned if you dont read the manuel)
