I think is a medieval game with sci fi elements, but I don't remember the name :\ please, help me search this game.

Might & Magic?

No, I know might and magic :\ but is a game with point click elements.

So more of an adventure game than an RPG? Or a hybrid like QFG? Betrayal in Krondor was a full on RPG I think.

How about the Death Gate or Shannara games? Or was it third person perspective?

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.

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.

Quest for Infamy? This one is from 2014, so I'm not sure how old the game you're thinking of it.

is Shannara, thank you all of you :D

Glad to help :)

There's also books and a TV show off Shannara.

This game is what got my wife into gaming. She still is looking for a way to save one of the characters. :)

I think you meant "Might or Magic"?

Then there are of course the "Heroes for Might or Magic" but they are strategy games.

To the OP, have you played the sequels like Betrayal from Antara and Return with Krondor?

albion or one of the ultima games?
