@clarity 7drl has had a lot of takes on ascii roguelike combat over the years that i found interesting, some that immediately come to mind are swift swurd and dead face
and there's a lot of potential for stuff without combat too, ultima ratio regum and the stealth 7drl lurk leap loot are the big ones that come to mind for me.
and while im speaking about roguelikes, one of the things that gets my brain juices flowing hardest with regards to the artistic capabilities of roguelikes is this old paper by Mark R. Johnson, who creates ultima ratio regum
