Yes and still under active development [1]! We also just finished the 2024 November NetHack Tournament (TNNT) [2]! I played in the tournament for the first time this year. I had one near-win with a very challenging Monk (I was doing a bunch of conducts [3]) who unfortunately died to the infamous Wizard of Yendor (Rodney as we call him). I also had a winning run with a Wizard which unfortunately finished a few hours after the deadline at the end of the tournament, so sadly that one didn't count!
Next year I hope to have a bit more time to play so that I can record a win in regulation time!
I do all of my NetHack gaming via ssh to Hardfought[1]. They offer the current vanilla and previous ones all the way back to 1.3d. However they specialize in variants. My favorite variant is xNetHack[2]...
Next year I hope to have a bit more time to play so that I can record a win in regulation time!
