Mobile games have pivoted from being short, fun to play vignettes into honey traps that lure you in and get you hooked to consume your time and/or money.

Every major studio out there makes formulaic bull that basically copies some other schmuck's idea and adds their own "StudioCoin" on top to monetize the game.

Temple Run spawned hundreds of clones, then Candy Crush clones came out and now apparently it's Clash of Clans clones. Everyone from EA to Mobage does this cloning instead of focusing on bringing new ideas to the table. If only they tried to innovate, the crappy studios like King would go out of business.

Indie developers try hard, but it takes a team to make a well rounded game with large scale mass appeal... :/

tl;dr Today's mobile games are time consuming black holes, and once done credible competition comes forth, they're sure sink.
