A bad business decision... I can't see any justification for the price hike. Content is not updated enough.

Absolutely agree. I unlocked a bunch of stuff via sharing on Facebook etc, was planning on buying a few remaining items but now I have to pay $150 / year?

Maybe in five year's time, there could be enough content to justify the pricetag, but if you plan to constantly add new content you could just go with a granular low cost in-app purchase approach in addition to a subscription.What guarantee do subscribers have on the rate new content will arrive? What prevents you stopping all development, sitting pretty raking in ransom fees from parents to retain access to the games their kids already love?
