Revolution! with Anarchy expansion: when does the game end?
I didn't find a copy of the rules, but the expansion seems to consist of a board that replaces certain districts like The Palace did. I don't see why the end-of-game would be any different than without the expansion.

As for end-of-game frenzy, there's always a lot of cube manipulations at the end of the game. The person in the lead tries to end the game, while the others are vying to move cubes instead of adding them (or they are trying to get the resources to win the roles that would allow them to do so). Nothing new here.
