AND will encourage social interaction... unlike Pokey-Go
Well, I'm not so sure about that. I'm in a young little city, with lots of families and college kids. It's not uncommon to hear someone of any age under about 40 call out some pokemon name in the common poke-areas of the city, only to have a few other people of varying ages say, "Oooh, cool. Where?" I'm not sure that outside the game that college kids would be making any sort of contact with 10 year olds.
This weekend the wife and I went to people watch at what was rumored to be a ridiculous gathering of players. We were not disappointed. A little park on the outskirts of the city had like 100 people there all milling around playing the game. Some camped out in chairs and on benches, some just wandering up and down the waterfront, people with dogs, kids in strollers.... It was insane. And they were talking to each other. Probably even splits of ages between middle school, high school, college kids, and nerdy 20-40 year old and parents. Somebody from one end of the park would shout that they found some pokemon, and half the people would wander down there, occasionally high-fiving random strangers when they caught it.
It was wild. I've never seen anything like it in my life. I'm guessing small towns are different, but around here, it really is a social game.
