World Events would be a nice addition to the game. Things like local crop failures, droughts, and positive stuff as well. Larger global events would be a nice touch as well, but at the moment I can't think of any that would work.
This kind of option could be selected at the game creation screen where you could choose no event, minor events, and major events kind of like what is available for monsters and shards currently.
(Disclaimer) I'm not a programmer so I have no idea how hard this kind of thing would be to implement.
