I don’t believe that ultra-predatory mechanics are long-term sustainable. They usually yield a “ring of fire” effect that creates a growing ring of users for a while but really you’re burning out all your core users and will implode. This is how many describe the original Zynga model.

Supercell (founded around the same time) has cultivated longterm ecosystems and IP by respecting their players.

EGG takes a similar long-term perspective.
