There's Nox Archaist, which has a very similar engine to that of the Ultima series (specifically 4 and 5, but without the first person dungeons).

Perhaps it might be worth knowing which CRPGs you did *not* enjoy.

If you like CRPG/adventure hybrids, I strongly recommend the Quest for Glory pack.

You seem to like old school first-person RPGs, so have you played Ravenloft: Strahd's Possession or Lands of Lore? Those are two of my early faves of that type, from right when I got into PC games.

Disco Elysium, Land of Lore, Stonekeep, Die By The Sword, Titan Quest, Legend of Grimrock, Planescape Torment, Temple Of Elemental Evil, Divine Divinity, Divinity Original Sin, The Quest, Mount and Blade series, Wizards & Warriors and Drakensang, all on GOG!!!

Pillars of Eternity.

(Warning: Lots of text walls in this one.)

Pathfinder: Kingmaker
Dragon Age Origin.
Grim Dawn (ARPG)
Divinity Original Sin 1 and 2
Greedfall

Jeff Vogel has to be doing something right to have stayed in business for over 20 years, so I'm suggesting Exile/Avernum.

If you can get it running, Exile is free these days, and all his games have expansive Shareware demos so you can get to grips with them.

Finally finished my Tyranny playthrough, was fairly satisfying.
It wasn't made 100 years ago like the other games you mentioned though.

Hi, great taste in games.

Consider trying:

There are other more obscure ones from long ago that no one has mentioned, here's one as an example:

As an outside-the-box pick, I think The Age of Decadence is one of the best pure role-playing games I have ever played, albeit it is different in style from the other games being mentioned.

Personally, I think

is better, and should be bought and played first.

Lands of Lore is great, at least the first one.

The first Witcher has rather old-school sensibilities so you might like it. It's one of my all time favorites.

Driftmoon is a very nice, charming game, also rather old-school though definitely much lighter and easier than those old games.

Ghost of a Tale isn't really a straight-up RPG, more like a adventure game/stealth/RPG hybrid, but it is easily the most unique, beautiful, charming game of the last decade, with remarkably good world building.

If you'd like to go more sci-fi, Deus Ex Human Revolution is fantastic game and holds up nicely. I recommend finding a mod for the Director's Cut that restores the original gold filter though. In this game, style matters.

The first Divinity: Original Sin is great fun. It doesn't exactly have a fantastic plot, but the gameplay in and out of combat is excellent, and the world is vibrant and entertaining.

If you like superheroes, especially older Marvel comics, try Freedom Force.

Wizards & Warriors is my recommendation

David Bradley worked on this after Wizardry 6 & 7 so there are some similarities but it has it`s own unique elements as well, also has a great soundtrack.
