Seriously SE???

c'mon give me an estimation more concrete, realistic and convincing than mine.
I can't be completely wrong here.

Legacy players pay $10 per month. It's also cheaper to pay several months in advance. 8M is a lot for 500k players. But you're missing investment time. These games take like 5-10 years to develop before release (it can take years to recoup these expenses). Server costs are hugely expensive and they are located around the world. You've got rent space, buildings, utilities, property taxes, benefits paid to employees (health, dental, life insurance, pension, retirement), composers, liability insurance, marketing, HR, headhunter recruiters, income taxes (International, US Federal, State), franchise taxes, the list goes on and on. Ha - you're missing a boat load of expenses.

Income taxes alone fractions your numbers. I think you need to do a little bit more thinking.
