Rocket League costs $20 when it's not on sale. Say you get 50 people to buy the game. That's $1,000 in revenue, let's say that 80% of that is profit. So that's $800 that Psyonix/Epic make. I would imagine the staffing costs to keep Linux and macOS versions of the game running are more than $800/week.
