I'm not at all a Harry Potter fan (read the first book when I was a kid, disliked it, ignored anything related ever since), but I did play a LOT of Ingress when I lived in Chicago, and still do play that a bit every now and then. Didn't really get into Pokemon Go. Also not into Pokemon, so I didn't care about it as much. I'm level 19 just from randomly opening it out of boredom, usually while waiting for a cooldown in Ingress, since the locations are generally the same.
I tried Wizards Unite the last two days and made it up to level 9. Not sure if I'll continue--waiting for the animations just seems really tedious, and again, not a fan of HP, so that aspect doesn't motivate or particularly appeal to me.
These are really winter sports when you live in Arizona and it can be 90 degrees by 10am, unless you want to play at 5am or late at night. Or walk around looking like an idiot in the mall, which I've noticed has a bunch of inns that I never noticed when playing the other games, though I may just never have checked.
Portals/Pokestops/Inns etc. are generally not as close together around me as they were in Chicago or even where I lived for a short time in Nova Scotia. Maybe the games would be more appealing if I lived closer to downtown and/or the university. I still have it much better than rural players, with a couple of small clusters near me, at least. There were two or three other people in the park this morning who were definitely playing one of the three.
