warp cores would be cool. even if they were just limited to a few types that would affect your power levels or power transfer speed. maybe a standard one, a few that add a bonus to certain power setting (ie weapons, auxillary etc) and one that increases the power transfer like an eps does.
Because it would be too much like star fleet command series?
They mentioned. Few years ago that there engine couldn't do that.
Meaning they don't care and won't do it. I honestly don't believe that their engine can't add a working warp core when they have universal consoles that add power and give bonuses of other kinds. Adding one more equipment slot for a warp core is not impossible. Of course this argument is as old as this game has been running.
