Toggling of creature spawn?

[IcemanX]

How about being able to turn on and off creatures showing up in a newly generated world altogether?

I could see using this to make the game more difficult,or make it easier instead,if someone wanted to.

For example,someone could disable Beefalo or Pigmen showing up to have a VERY hard survival out there,or disable spiders or hounds if they just couldn't take it. Also,you could modify the xp gained/rewards based on how many things are turned on, along with the "How many days did you make it?" System already in place. That way people still have a reason to play the game "How it was meant to be played" for the most bonuses, But can still enjoy it another way.

I think this would turn the re playability up quite a few notches,with hardly any changes game-wise.

Alternatively,you could have the option of something else filling the void,such as more rabbits/hostiles? Although I'd still enjoy it if it were just..Blank where those things would have been.
