Any Sci-fi games with....

Balkon

Are there any sci-fi games or MMO's, that actually implement Antigravity ships (Like Flying Saucer type)?

Every futuristic game I play is just space ships that look really advanced (Like Star trek/wars and Eve online).



And I'm not talking about some little kids flash game, more like a game that seriously tries to implement a alien-like zero point technology that you can build/upgrade/change.



I cant find any, and I dont know why not, theres tons of UFO buffs who would buy it just to have it.



(And I know about the UFO: 'Series', thats not what I'm looking for)
