One method of helping both multiplayer and singleplayer would be to have an option to play under a handicap (rather than boost AI resource and credits cheats to new levels). Thats why it might be useful to have four divergent forms of each faction monarchy, theocracy/oligarchy and republic, with anarchy being a handicap form. Faster play won't encourage newcomers, while a method of being able to play at a more equal level might.
The devs will simply never be able to allocate enough time to produce a competent AI. The only method to achieve this is to make the AI script and variables open to the community, allow competing player-created AIs to emerge and have a game type where they can fight. Then AIs much better than the standard types will emerge. Hard-coded AI is a major disadvantage.
If there is the option to alter the engine at all, then priority might be allocated to hiding, having very little element of tactical surprise isn't good. Even if hiding can't be made to work, how about camouflage.. units that resemble trade ships to enemies might be very effectively hidden?
Wasn't xenophobia and intercultural competence going to be a large feature of the expansion? Limited feed, especially between unlike factions, should have a huge impact on the game...?
Have the Illuminators been fixed in the beta...????
