Endgame map needs changes

I finally managed to complete the event map called Endgame. It took 24 days because I was the only player left since day 3. And because none of my allied AI did anything at all. One of them was attacked, but did nothing but stand idle and it didn't build anything. My other ally did nothing at all and never went to war.

As a consequence, I had to fight 6 nations alone and combined with a lack of interest for a game where I'm the only player, it took really long time.

If Endgame goes up again, it needs some kind of solution to this. And above all, there should be a way for the last remaining player to end the game with a win if his coalition is leading.
