This really does not sound healthy. The game is released, for a certain amount of money. If people don’t like what they get for their money, they simply should not buy it.
But by now gamers have been so trained to expect to endless content treadmills and all their ilk like mtx and battle passes that publishers/developers get egged on if they don’t work on their game 24/7 and forever.
It’s a tough line to walk. You want to create reasonable hype and you have an idea where you want to go, but as you correctly point out, it’s really easy to over promise and under deliver.
