human
recreate earth with no humans, pure and untouched nature to work with
change human parameters to as follows
set hardcap on pain much lower than it is now, same with fear and other unpleasant sensations/feelings
no need for food and sleep although can eat and sleep if you decide
no need of going to a bathroom, also humans are always clean and smell good
invulnerable, yet feelings and sensations are still present to make life not so dull and boring and to add some action, invulnerable also means no diseases, substances don't work, no aging past certain age etc.
no universal anger, animals don't try to attack you

spawn myself in this world as a human
bring some good and kind people from our current world to mine. 
live together, have fun, play games, do handcrafting, art, music etc. travel and explore the earth, enjoy the beauty of nature

then probably add some mechanic of reincarnation so that if you decide you lived long enough you can leave this world and your body dies, then you chose: your memory gets wiped clean and your consciousness then will be transferred to a newborn baby, or you can stay in some sort of transcended nirvana-like state indefinitely

It sounds so sweet a vision. We could craft all the thing we please and it wouldnt constantly rot and be invaded by moisture like in here.
human
flies, mosquitoes and maggots abolished. Basically a world free of any parasitism but only cooperation of all

nah nature can stay as it is, just humans getting a more pleasant experience and basically being more of a spectators then players. flies, mosquitoes and maggots won't bother you and cant do anything to you, so whatever.
also I don't think that things should be unbreakable, humans successfully survived with their primitive tools that constantly rot, and here you basically doing it for fun so I don't see a problem, it just adds more action to the world because you'll have to repair something/craft something new
