Hm, with point and click elements? Betrayal at Krondor and QFG were very different games, so it's hard to figure out what you're looking for.
With the combination of fantasy and sci-fi elements that you describe, the only thing that springs to mind is Albion. https://www.gog.com/game/albion
Not sure that's what you're looking for, though.
Edited to add: Wizardry 8 (https://www.gog.com/game/wizardry_8
) also fits the criteria, but it's quite a bit more modern than Krondor or QFG, so I'm guessing it's not what you're looking for.
