Have you ever played Dungeon Crawl Stone Soup? It is a roguelike turn-based game very similar to Nethack.

I managed to win the game with a 15-rune victory as a draconian transmuter of Cheibriados the God of Deliberation. Low and behold, I was lucky enough to find a Wyrmbane, one of the best weapons in the game.
