Do RPGs with Quest elements count?
If so, it's Silver. One of the first games I've played and still one of my favorites. It's a European attempt to create a jRPG with some Adventure game elements and a unique battle system (you have to move mouse in certain directions to hack, slash, stab etc.).
This game has everything - great story and setting, perfect gameplay, beautiful pre-rendered graphics, one of the best music scores I've ever heard in video games. Back in the day it was a real pain in ass to get the game to launch and play without crashes, but now the game is available on GOG.com and most bugs & crashes are fixed.
Totally recommended.
