> There are people who will spend well over $10,000 a year to fulfill their compulsion for their "chosen" game.

John "Rotten" Lydon is a famous example:

  I wasted – you’re the first to know this – 10,000 f‑‑‑‑‑‑ pounds in the last two
  years on apps on my iPad. I got into Game of Thrones, Game of War, Real Racing,
  and I just wanted to up the ante. And like an idiot I didn’t check myself. I’ve
  been checked now. But there's a kid in me, see? A bit of my childhood was taken
  from me and I’m determined to bring it back.
