I completely agree.
When my brother and I play it's always a tough call to decide wether or not we have definitely "won" and can safely exit without missing out on a couple final epic battles with some hidden fleet.
A couple things would definitely help with that (and fit nicely into the next diplomacy xpac):
- an obvious readout at the top showing resource income, fleet strength, and culture strength so we can eyeball progress - the galactic rumor mill ought to cover this sort of thing
- the option to check off those extra win conditions based on that info.
- make cultural domination directly useful to game speed as well: IE planets with very low allegience don't commit self-genicide, but instead become nuetral, than if the enemy culture remains stronger simply switch allegience whole hog. Attacking a nuetral planet counts as HUGE propaganda against your culture and will make it switch nearly instantly (hey, they're trying to kill us, get help!) If your cultural takeover is fast enough, you might even be able to stop them from scrapping all the buildings.
- make econimic domination directly useful to the game speed as well: let buying metal and crystal from the black market actually reduce the output of your enemies refineries in some way that scales appropriately based on number and allegience of refineries (after all, it does represent resources being sold on the sly - and improve trade among allies and bonus for extra trade posts - thus when your team owns 3/4 of the trade outposts your team is getting 3/4 squared trade income, while your foe is only getting 1/4 squared.
- the ability to give teammates ships and planets (thus keeping "eliminated" PLAYERS in the game and simplifying combined fleets, without making it slower) although some things would need to be polished (specifically, all buildings at planets you own need to use your logistic and tactical slots)
As for the other end of faster games - a faster start - I started one of the small maps - I think point blank and it gave me a bunch of frigates right off the bat.
So clearly starting fleets and additional planets are possible, and definitely would help game kickoff.
The only question would be which caps? Or just start with cap factories.
