MME
But semi-random MEE surely isn't a change that gives the most bang-for-the-buck .. declare war on all AIs you encounter, and you'll have a likewsie enjoyable game
My 0,02 EUR of thoughts:
small change (?)
fix the ministers
medium change
fix the rest of the AI
really big change
give ua SEV, with all the good stuff from SE3 back, e.g. right-click, loadable ship styles, inteligence etc. etc.
