lol... hooray for REALISM!!! Let's all die of old age after so many in-game years! Let's be coerced into paying taxes or having our characters thrown in jail! Let's NOT be able to catch a wild rabbit by walking as CLOSE TO IT as possible, then grabbing it!

hehe, i'm just messing with you. Crop disease may not be too terrible, so long as there were ways of dealing with it, and it wasn't just a random "oh, by the way, your food supply is all dead. and so are you. BURN!". Maybe if you implemented compost or some kind of natural pesticide based on current objects (i'm not even gonna try to come up with an idea for that one... you guys figure it out if you want)... Then if you just were a lazy farmer, you'd stand a higher risk of losing crops. Beehives could work in there somehow too maybe.
and, oh yeah.... ahem... existenzialism... um.... errrr... i guess sometimes I feel a twinge of Sartreian nausea when I can't decide what to do next... Silkworms are all happy, food supplies are high, fence is all done, saplings and crops are all growing... But then I just log out and eat a cookie. So the game really is fundimentally anti-existentiallist since you can always quit and come back to it, and play the game on your own terms without being forced to act or die. But then again, so is every video game. Guess that's why we play them.
