Looking for something like it but more modern, and if it's not a dungeon specifically that's fine. For example, I was really tempted by "Evil Genius 2" it looked like it hit some of the itches I am looking to scratch (metaphorically of course) but I was turned off when I saw it utilizes Denuvo.
Any recommendations, or remember the name of the DOS title I am thinking of? Pretty sure it was popular enough to be on GoG but I just canna remember the name for the life of me. Think dungeon something...
That's probably what you are thinking about. If so, there's a couple games that might suit your fancy:
War for the Overworld
KeeperRL (Pixels, top down.)
Starship Troopers: Terran Command. (Maybe. Very different.)
Not familiar with the titles you recommended, but really looking forward to checking them out. Thanks!
