Fair - I king of lost interest in Pokemon Go (I'm assuming that's the other one you're referring to) as I couldn't play at work - and often didn't have enough time in the evenings to walk. I was constantly running out of balls - and I am one of those sticklers where if I can get it for free then I'm not spending my money on it! lol
But I also never really watched Pokemon as a kid so I didn't have the same interest - where as Harry Potter is a whole different story!
