A friend worked for a company that has games where you farm in villas and say words to friends. He said in those games sometimes for months product managers would be focused on certain users (often 1-3 users) rather than the larger audience. He said there was an old lady who was somehow spending 5 digits dollars a month on their platform and he was kinda the dedicated developer for to her for quite some time. Features were built keeping just that user or few users in mind. Specific plot changes were added, resource changes - sometimes across games where this user would play. He said pricing of purchases were also changed for that specific customer compared to others. (This is the gist. It’s been some time so I don’t recall exact details)
