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.
Because it is a much safer investment to send out a 50% costed demo to see if you can break into the market then trickle out updates to make up the rest of the cost
If your demo doesn’t land then you’ve saved half the cost of a full project that would fail anyway
Good luck trying to win market share with a half baked game.
