Only way this could be any better is if the tools/items boosted skills over ten. Like weapons (little target) is at ten, but adding a pistol makes it eleven.
ok i know this wont make much sense but
infinite/infinite less than infinite. i.e. the biggest possible amount in existance over the smallest possible amount in existance
here's a good challenge.
Go through the entire game (any difficulty) only using your original: pipe, shirt, pants, shoes, attack abilities, and any passive abilities.
