You meant a whole new game, ala
Elements The Game: Galactic Duel
Or some other byline...
Would be cool. I thought maybe you meant like a skin. Like you buy the future skin and it turns everything into spaceships and robots in the art, but the gameplay is exactly the same otherwise.
Also, to be fair, there is already quite a bit of scientific/scifi parts of elements. Nova, Supernova, Blackhole, Gravity the element etc... I know it isn't alien races who drive spaceships made of platinum or living organisms that eat planets or anything like that but...
