i think space wise it's quite balanced but ground wise not even close, i think rebel units should generally fight a bit better kind of like guerilla fighters do generally being better in they're setting...like wooden areas, urban etc. so if your near say trees you'd get a big bonus, while imps would get it in open areas. other things that could be changed is prices...i know it's realistic, but i had a bit under half the gal, and got 3k...for a space ship that costs 50k.. if i lose one of the beginning ones im in for a looooooong wait. i realize it being higher is very good as u cant just mass ships like u can normally. oh and tech lvl should start at 1 imho.
