The answer to your question is those were unsustainable business models, and thats also why they failed.

To my point, cell phone games are a perfect example. Free to play games all fucking suck now, and nobody wants to pay for games so much, so developers don’t really focus on paid games, just paid upgrades, and promo packs etc.

I say all this, but I also recognize Freeware was basically pay to play/dlc also, and i loved the freeware method.
