I shouldn't have to explain myself as to why you shouldn't edit a game about survival and collecting stuff, or any working game for that matter.
It's not broken and it doesn't need fixing.
My chair is original. Does this mean I need another chair? Explain yourself.
Okay, so imagine you have a 1-year-old car that runs relatively fine but isn't particularly stunning in appearance.
You add on some spoilers, get some custom hubcaps, get a better engine, get a new paint job, etc.
None of those things are necessary, but they can make it look and run better.
Also, what's wrong with adding more things to survive from and collect in a game about surviving and collecting?!
