I agree with Blargerist, the main issue with SoL is there is no scaling in it. If you have a bad start and cannot find the required 7 types of food before the first night you are almost guaranteed to die to starvation. Now I do get the point of it, namely to stop people just relying on one food type for the entire game but without scaling it just ruins the early game.
Maybe give it a delay? say no issue first couple of nights but after that each subsequent night you have to eat one more food type. That way it does alter food late game but allows people to survive those first nights bit easier.
