Using leavers spot !

Hello all, I want to share what I think it would be a great idea to keep Casual games great and more interesting:

In the case of someone leaving the game it would be interesting if the territories became "frozen" for one or two turns so someone else could substitute the original player, an example: we are playing a scenario with empires and sudently Russia leaves, if someone out of the game could join and keep the lands of Russia the game will not be ruined in that point. All other games to, scenario or not, would benefict if that mode could be a reality.

That requires work
