What other Roguelikes are as good as Nethack?
A couple of weeks ago, I got the urge to get into classic Roguelikes, and looked up which ones were popular. I tried Tales of Majeyal, Coves of Qud and Dungeon Crawl Stone Soup. But none of them fully clicked with me in the short time I played them.
Then I remembered Nethack and decided to give it a proper try, after playing it very shortly 20 years ago, and this time, I got fully immersed. What I really loved were the identify mechanics, the survival elements, the great replayability and the high level of surprising complexity and interactivity.
Now that I know that I really like the genre, I'm wondering if the other games I tried are as good as Nethack and I just didn't stick with them long enough. Which classic Roguelikes are on Nethack's level or beyond?
