You are right on the cusp of realizing that any company making a profit has by definition underpaid its workers for the value created. You are SO CLOSE to figuring out that all profit is stolen from workers. Yes even the "rank and file worker bees" that for some reason you think don't deserve payment in relation to the company's income.

I realize that. However, I do not run Gamestop, nor any business for that matter. And that still doesn't explain how you expect a company to pay their employees based on revenue, instead of profit or some other measure that wouldn't immediately bankrupt the vast majority of companies. Thanks for playing.

Significantly improving the loading time, an allegedly huge gripe for many players of the game, and given no other dev was capable of improving the load time, that is a huge amount of value provided. And yes, given how successful the game was Rockstar should provide him with a larger reward.
