PoGo was total buttcheeks. They failed on too many fronts with that game. They almost had the world addicted in the first 3-4 weeks, but a few dumb moves over a couple weeks and 90% of the people I knew had stopped playing it. Went from like half of the town out and about on the weekends for catching pokemon to maybe 5% of the town in a matter of two weeks. My wife noticed it too.
It was fun for about a month, but they were too busy trying to launch it in every country, removing features, and disabling tracking apps INSTEAD of adding live pvp, trading, shiny pokemon, or legendaries like zapdos or mew, all features I know my group was crying for. SMH PoGo is one of the biggest fails ever.
Sure, they will keep the 1-2 million people playing it for a while, but when they start releasing those weird new gen pokemon, I have a feeling even more people will drop the game. Just like the game boy games, red and blue were good, gold and silver were cool, but kind of the same, and any games after that were just getting old, people got sick of it.
