That might be tricky. Imagine there is an absolute amount of requests a single player may be able to send just by paying the base game. And now you times this by six to get your max requests per game. But it might also be enough to let 10 players play a “normal” game. So you either lower your limit further and therefore make the game worse for some player or you leave it up there and may not achieve anything.
Couldn’t they just rate limit requests like every other API?
