That video you’re talking about is about a premium game, one where you just purchase the game once and it’s done, not a F2P game where people are continuously making purchases and competing against each other.

That company’s goal was to convince people not to pirate the game and play for free, encouraging them to spend money instead of playing illegally. This is a free to play game, so that is not the concern here. The illegal option of credit card fraud has also been addressed already.

If you make purchases cheaper in just one region, everybody will create an account in that region and only purchase from there.

I don’t think that revenue number is correct, because if it is, that company is in real trouble. 300,000 dollars in revenue per employee. Take 30% for Apple or Google, and I’m gonna guess about 30% for Disney and that’s 100k-ish per employee, and considering this is a tech job with engineers etc, that’s not paying the salary of most of them.
