Shoutout to Caves of Qud, because it wasn’t mentioned yet. I’ve been looking for a game that comes close to ZAngband which I played in the 90s. COQ has a tileset, so it’s not ASCII and I didn’t like the looks at first but it’s fun when you see how deep it is. Complex character creation, quests, factions, ‘bosses’… I think the world map is not randomly generated, the rest is afaik (ruins, multi-levelled lairs, most villages…).

I think there is a tree hiding behind an owl.
