This is not a game for the "power gamers" who want to level up, get gear, level up, get gear..and win. And I think they are finding that out, they can powergame themselves to have very high CP pokemon and rule gyms but then someone who took 4 times as long to level up and get their pokemon comes up and drops them. It's almost very anti-power gamer..haha!
They used cheating to get themselves all the best pokemon that they needed, and now they "fixed" the cheats and they cry that its boring? haha
This is still a very fun casual game that you can play with your family.
There is something unique to this game in that it solves something that the gaming industry has so far failed to do: encourage exercise and real social interactions. I mean actually interacting with real people, not trolls hidden behind their keyboard with large epeens.
It encourages you to go on walks, travel, actually interact with the outside world. That's been the biggest thing that this game has done for me and my kids. We now go to different areas and walk around. Sometimes its to parks, sometimes downtown, sometimes to waterfalls, or any other random public place that we typically don't go. How many other games actually encourage being active, and being outside your basement? It's also a bit like fishing, seeing who can get the highest CP pokemon.
Like it or not the latest generations (at least) sit more and exercise less, and video games worsen that as they encourage the kids to sit in a spot for 10 hours. Whats that? Force them to go outside and play? Some kids really aren't athletic or have a desire to be..and as a parent you could force your kid to exercise but that doesn't really work well. Sure when I grew up I was outside all the time..but then I grew up in a rural town of 28k, where all the housing and streets looked straight out of Leave it to Beaver. My kids are growing up in the inner city, and I'm not so concerned about kidnapping etc. as I am them having to cross dozens of intersections.
So yes, I'm sure the "fad" will fade a bit as it's newness loses its luster, but considering the unique benefits of the game it still is a fun, cute game that encourages social interaction and physical activity.
