If you aren't looking for specific gameplay and you're just making a long list of WRPGs no matter the style, here are some more that I think haven't been mentioned yet (excluding modern 3D FPS/TPS RPGs and tile-based dungeon crawlers):
Real time / ARPG: Revenant
Soulbringer (might not run on all newer systems)
Driftmoon (more like an easy Zelda game with more story, Narnia-like Christian background that bothers some)
Rage of Mages 1+2 (scenario-based, RTS crossover)
Evil Islands
Real-time with pause or optionally turn-based: The Witcher
Neverwinter Nights 2
Knights of the Old Republic 1+2
Arcanum: Of Steamworks and Magick Obscura
Vampire - The Masquerade: Redemption
Serpent in the Staglands
Turn-based: Fallout 1+2 (post apocalyptic, not fantasy)
The Temple of Elemental Evil
Dark Sun 1+2
Knights of the Chalice
Shadowrun series (cyberpunk, modern fantasy)
Torment: Tides of Numenera
Avernum, Avadon und Geneforge series, Nethergate: The Resurrection, Queen's Wish: The Conqueror
Eschalon 1-3
Underrail (post apocalyptic, not fantasy)
Albion (with some arcade-y action sequences, combat takes place on a different screen)
Balrum (with crafting)
Aarklash Legacy (combat mostly, foxed characters, linear story, not much else)
Careful with these two! Shadows: Heretic Kingdoms is actually an outdated version of the first part of Shadows: Awakening. You most probably wouldn't want to spend 30 dollars on getting only half of Shadows: Awakening just to see what it was like in the old engine. Frankly, I think it's rather shady that GOG allows the publisher to keep this up on the store page without so much as a warning. This should be included as a bonus to Awakening at best.
Get Kult: Heretic Kingdoms and Shadows: Awakening, but
NOT Shadows: Heretic Kingdoms unless you're a collector or interested in the history of the game's development.
