Nuclear engine vs combustion?

Yes and no, the tanks in dust should be more technologically advanced than what we have now, no question about that, but 20000 years is a bit of a stretch. If you know about EvE's history the colonies went through a dark age after the gate closed, going all the way back to near stoneage levels, if they even managed to survive at all. The big 4 Amarr, Caldari, Gallente, and Minmatar, discover space travel and throw all their money into that (amarr kinda forced space travel onto the minmatar they were still just exploring their own galaxy when the amarr showed up and "enlightened" them)

With the sudden interest in space travel, and hence combat ground technology probably took a bit of a hit in advancement, why worry about tanks on the ground when you can just bombard a planet from space into submission. Add into the the advent of empyrians (aka capsuleers) and more tech is thrown to space and less and less to ground warfare. Not to say that ground warfare wasn't important but empyrians being unable to die pushed the focus of technology to their area.

Add in the dust mercs and there is a sudden push for advancement in ground warfare but this push is rather recent, most of our tech is either new weapons that are too dangerous for normal people to use or an old vehicle with starship grade weapon systems strapped onto it.

TLDR:
yes our tanks should be more advanced than the M1 abrams, however its nowhere near as advanced as amount of time between earth and eve is due to loss of technology and advancement from the dark age periods.

Nuclear engine vs combustion?

Also I'm gonna say it again here like I did in all the other 40 threads....

Webifiers --Look them up, cause they are coming someday, which makes this request a redundancy that will probably never be taken seriously.

BS, have you seen the nutty physics in EVE? Because nothing in EVE makes sense and nothing in a Science Fiction Video Game about Immortal Mercs in SPAAACE has to be accurate.

So why do all you meat bags from 2014 Earth give a random rat turd about this?

This Is A Video Game! Not A Simulation! Play The F*ing Game!

If you want simulation get out of the space dust.
World of Tanks sounds like a much better solution for QQ of this level. Seriously.

This is not a very good FPS and is riddled with problems. It is a 5/10 FPS about Immortal Mercs In Space and some of them drive Tanks. Some of those tank drivers are actually quite good at it. While many AV players, if not most, want a Push To Win Button that will Kill That Freaking Tank Right Over There.

Why don't you guy do what has been pushed at me? Sit down and see how 1.8 turns out?
Then AV QQs should be legion.
