I voted up the ideas I really like but couldn't figure out how to leave comments on the cards as I can only vote and watch them. So I'm leaving my feedback here.
-Tidal wave: Sounds great maybe it also has a chance to wash stuff up onto the land?
-Earthquake: Maybe can also uncover other veins of ore around where the land changes?
-Crab invasion: no complaint could make things more challenging.
-Lightning Storm: Would you need water stored up to put out the fire or would you just use a character's time to put them out?
-Crazy Vegetation event: sounds cool
-Storm warning: SUPER USEFUL, maybe you have to have a specific building like a lookout tower to get this benefit?
-Permanent food info: Another really useful thing to know.
-Skill Tree: sounds like a good feature
-Food Item Priority: Can't tell you how many times my people ate my grain and left me with nothing left to plant...
-Map Editor: A much needed feature for the game to live longer.
-Itinerant salesman, seasons, and food points: All interesting and fun ideas.
The only 3 ideas I am on the fence about are Diseases, Temperature management, and Water Management. I think they could be interesting if you could automate some of them by building a rain collector or maybe being able to farm the medicine after collecting it.
