What’s the difference between predatory tactics to hook people into a game, and “normal” gameplay, whatever that is? If neither cost any money or have microtransactions in any way?
Is Diablo 2 using predatory mechanics? Is Counter Strike? Is Factorio?
Games are artificial constructs. If you deconstruct them entirely, unless they got some story to tell as the center point of the game, their mechanics and goals are entirely artificial and constructed to get you to keep playing, be engaged, and have fun, whatever that means and implies.
Because, well, in the end, games do not have a grand purpose. Their purpose is entertainment(or be art, but not all games have that goal). And so if vampire survivors keep you engaged and enjoy the game… Is that really that much different to other games? Another example to this are idle/incremental games, as a pure distillation of what games are. Are they predatory? Is there really much difference from the very core of other, more “proper”, games?
