What happens when a game ends on turns.

I have had a couple of unusual endings, so I want to make sure I am now clear about what happens when a game ends on turns.

1. Only the individual with the highest sp wins. (It doesn't matter who is allied with who. The allies of the sp leader will also lose.)

2. If the sp leader is eliminated on the final turn (Turn 51 of a 50 turn game), everyone loses.

Any other weird endings I should know about?

Highest SP player wins it doesnt matter if he is allied , also if he is elminated before last turn next player with highest sp wins
