It was a lazy cash grab. They outsourced it to the same chinese company who‘ve made plenty mobile dota clones before. They dumbed down their usual game and slapped pokemon skins on it. It‘s a fairly awful game.

Then there‘s PokemonGO which had a rough start quality vise. It was also outsourced but at the very least it was successful and different, though way too simplified for my taste. Of course I‘m one of those conservative gamers who don‘t want to point their camera at virtual things outside so I‘m a little biased I guess.
