If you like these kinds of games but find SPD to be a little too mechanically simple and lacking in build diversity, you may also enjoy DCSS (dungeon crawl stone soup) and my personal favorite: Frogcomposband.
You can play the later at angband.live, and it's an exceptional game with incredible depth and variety.
