It really depends on how you define "scam". It's not a scam by how I would define it.
With the loosest definition possible, sure. I bought into a scam. I'm not a fan of all their marketing tactics.
But the game is playable enough for me and I really enjoy playing it. I did my research and I knew what I was paying into at the time. I've gotten my money's worth already and I'm still enjoying it, which is a lot better than what I can say for some other games out there.
