I used to be into Pokemon when I was younger, but I'm not really into it anymore. So I didn't really care about the app, but then I downloaded it anyways. I found out that my phone "Iphone 4s" does not really work with the app, so it crashes any time I get a pokemon XD. So I have it, but I never use it for that reason. I wouldn't actually mind playing it every now and again though. What I would love to see, is a Suikoden version of Pokemon Go! That would be amazing, each game has around 108 characters to recruit and there are 5 games, plus a couple of spin off games! Some fans have already made fan art of a Suikoden Go, or SuiGOden. lol
Some of my friends who actively play it, have said that they're grateful for it because it's making them become active. One of my friends has been wanting to lose weight, and she's really glad they made the app.
