I used to play this game called RAGE many years ago. It was a first person shooter, with a bunch of late game overpowered guns, had a crafting system to make ammo and the like, shops to sell and buy said ammo, but had strict resource controls to keep it competitive and fun.

So I spent around four days tabulating values of every ammo and crafting material in the game, mapping out which in-game traders sold what and when, and then spent maybe the next three days just craft-selling the cheapest item, a wingstick(basically a boomerang) in the game.

Hundreds and hundreds of wingsticks, grinding like a little kid in a sweatshop. I made enough money to max. out capacity on every ammo capacity in the game. As a result I breezed through the endgame, and what was supposed to be a long, tough, engaging mission into the heart of the enemy turned into a caricature of a boss fight, and I probably spend more time admiring the environment design there than worrying about dying or running out of ammo. I think I ran out only on one ammo type, and in total I used only the three most powerful ammo types in the game.

A level I should have enjoyed and formed the neat little bow for that game to be wrapped in, turned into a comical doom guy-esque slaughter of the scariest enemy in-game.

I am truly my own worst enemy.
