Usually happens when a game was good initially, but then publishers get greedy and push RMT/pay-to-win/freemium features to please investors.
Maybe not a great example, but I played Eve Online for many years, and while the game is actually very playable with RMT (it feels fucking great to destroy somebody’s virtual property they paid 20$ to acquire), it kinda got out of hand and diminished the thousands of hours I put into the game.
