TheMonkofDestiny: Some good titles in the list, but she has a pretty big caveat in her initial post:
edit: nothing outdated
TheMonkofDestiny: Knocks out quite a few (not including Duke 3D, which is no longer sold here - thanks a lot Randy!) you mentioned, unfortunately.
Some have modern versions, though, and it depends I guess on how she deems a game to be "outdated". :)
Also thanks for reminding me about Duke3D.....I forgot it was delisted as I still see it in my library and forgot.
===================
GenlyAi: You seem to like Pillars of Eternity1/2, Tyranny and similar games, so I'd suggest:
Pathfinder: Kingmaker (a bit different, have you tried?), the just released
Disco Elysium,
ATOM RPG. Still isometric-y: if you like (or never tried) Commandos like game style, aside from the
Commandos series of course, there is
Shadow Tactics: Blades of the Shogun (really good).
I'll check back later and update my post.
I never played it but I second ATOM RPG.....looks very good.
