How early is common to win a game on endless?

Is the food urkan worth the effort? Aside from the boost to military strength. 

How valuable is the ELCP? The base game, with dlc, seems fine enough to me?

Is it possible to continue a multiplayer game after the victory screen? I know the 'continue playing' option exists for single player, but I don't see it in multiplayer?


If no, is it possible to move your faction from the second slot to the first slot? My friend started a mp game and invited me, but the AI worked his cheeks so I had to finish alone. I've already won, but I want to test some things out with my current build and I you can't play single player with a faction in the second slot. It forces you to be the faction in the first slot. 

The last two questions are part of a separate post if you want to answer there:
