I was actually a beta tester for the game. You will not believe how crazy evolving was then lol. 314 candies to evolve pidgeotto and you only got one a catch. It's not nearly as good as I'd hoped and they replaced the number of meters a pokemon is from you with those little footsteps, which I find inconvenient. And they don't seem to actually have taken much input from beta testers even though they did ask for suggestions, they could have at least given some indicator of a direction. But overall its not too bad, my boyfriend loves it.
Now, I'm a pretty extreme introvert, I actually may have social anxiety, so I don't really like it too much anymore. I like having walk arounds but I can't really deal with people coming up to me and talking about it or shouting out to me about it. I really preferred when it was in beta and only like three people nearby had it and no one really talked about it. The whole social aspect is kinda ruining it for me.
