Agreed. I have more hours in DCSS than any other game.
I don't think it's totally fair to call it ugly either. It's a masterpiece of efficiency. The ASCII looks messy to some people, but after a while you just see right through it; purple Y = catlobe gtfo etc. Plus the upside is that it's extremely clear at a glance what is going on because you don't have complicated sprites everywhere. And the handmade vaults that get rolled into the procgen are often really nice looking and give the world a lot of character.
Ok but elite:dangerous on VR with a HOTAS is pretty cool. As is the sculpting software that's out there.
