Minimalist Run

Minimalist Runs are getting through the game, with as little as possible, if you don't need it, dont get/do it. This is almost the exact opposite of the 100% Completion challenge, but generally isn't possible to get 0%

Examples
The Legend of Zelda quite often uses this challenge, as well as the Metroid games. These are normally done by not getting new weapons and armour, and forgoing health bonuses. Diablo took it to a new level, where players could search out cursed items, which would lower the base stats
