The game that just ended (the one in winter), I can view diaries (though it appears only I wrote anything?, only my own family is listed at the side), also, there's no way to see the final town, so I don't know if I won it or not, don't know the final standings - did both families get killed off in the same turn, did I win, did I come second?
So viewing diaries, as well as being able to view the final town would be good. (as a possible extra, you could have a marker for each family that says which day they were wiped out on).
