Both of your points are only partially correct.

I think we can state as a truth that they have less potential profit.

Wrong, they just take less effort and have a more constant revenue stream.

Potential for profit means nothing, when so many attempts at milkable forever games end up like Suicide Squad or Concord.

Also you can come into them half baked and pull the plug if the game doesn’t sell (because it’s half baked) like they’re doing with SS and they did with the Avengers game.

They spend more money.

They don’t, you can’t spend money you don’t have, whales are working adults.

Kids spend money for less. Better ROI, not higher payoff.

You make the 18302nd skin and troves of kids will badger their parents for fortnite bucks so they can buy it but not everyone will. The upside is that making a skin costs you single digits percent points of the profits, so even if one or two are a dud, you’re fine, the good ones will make up for it.

It’s a business model you can throw money at once the game’s got an audience base, which is very attractive to companies, because it’s uncomplicated and reliable.
