Nethack (which in my opinion should be the starting point of complexity for a new roguelike game).
Har! In that case, I can't think of a single Roguelike from the last 20 years. Even Angband doesn't fit the bill
In all fairness, you probably just had a bad day. Jere was obviously
not touting light/darkness mechanisms as something wholly unique, just a feature he'd given a bit more attention than the typical basics (tiles being lit/unlit). Apart from Golden Krone, the only RL I can think of that did anything particular with lighting, would be the 7drl Madness. So it's definitely something that sets GK apart, and there's nothing weird about discussing the particulars. There was
another vampire-themed game with light and darkness featured in the less known "Procedural Death Jam" some years ago, that was quite fun (not a Roguelike, though, but a puzzler with random levels).
As always,
