I totally agree with the saves suggestion. What I'd like is that when you exit the game you could save it as "whatever you want to call that save" and there shouldn't be a limited number of saves. That way everyone who wanted to could have a go. At the start you could also have a "load previous game" option and name the game you'd last saved, like you can do in many other groups.

I was having mouse issues and it started over instead of changing tribes! And I lost them all.
