Well, there will be other issues you can't control but you got to deal with.
I don't remember if it was a video or an article where they talked about it but...
...the seasons will have different impacts on the planet. For example, a normal winter is 3 months but it can happen that a winter takes 5 instead. You'll have issues with food reserves, crops not having enough time during the short spring/summer to grow and other "natural" disasters you'll need to react to.
About wars, I dunno. I do know they'll implement "Aliens" coming to your planet. That would be a war that you can't avoid. So, going all friendly might not work cuz they shove a military conflict up your arse that way
The whole idea has potential and I'm curious to see how it pans out. Money wise it looks good for them, I guess. Few days to go, main percentage of money reached, the last days on Kickstarter are always the busiest. Looking good for a successful campaign.
