I would try playing Dungeon Crawl: Stone Soup instead. It's another roguelike that is heavily inspired by nethack but is more modern and more beginner friendly. I love nethack (I've ascended twice) but it's definitely showing it's age (not to mention that the game is pretty broken in some regards). Crawl has a better interface and tries to remove all the tedious parts of roguelikes, though there's still a learning curve.
