> Isn't "It may just be a game to you, but it means the world to us" the grammatically correct form?

Yep, that's what I would go with. I can't see a use case for a comma after the "but" in British nor American English.

> I guess people feel like they would speak the sentence with a pause after the conjunction

Even this feels off to me when I read up to the "but" and then pause (as opposed to pausing on the "you").
