New idea. Uncharted space.Sounds a lot like horizon.
So largely the formula of uncharted is preserved. But this time the story takes place thousands of years into the future after the rise and fall of some future ancient civilization. "Drake" is still a treasure hunter but instead of the ruins being all sticks and stones modern and even future technologies become fair game(play). Portals? Of course. Gravity guns? Why not. Original ideas? That's up to the professionals…
I think we need aliens.
