I don't think mobile games are really the WORST things ever, The Steven Universe game "attack the light" was really good, and so was the Rick and Morty "Pocket Mortys" game.
I think mobile just deal with larger quantities of #####tier shovel-ware games that are for squirted out for quick profits from ads or micro transactions. The complete lack of content quality control is what makes for this influx of garbage filling the space.
I think I'd like mobile games more if there was more assurance of quality, and if the only times I'd play mobile games weren't "when I'm taking a crap" or "When I'm on the public bus," The latter of which makes me carsick.
Plus, the mobile space gives established, big name developers chances to find creative ways to share content otherwise long forgotten by the masses, and generate revenue whilst doing so...
Actually, Never mind. Forget everything I just said.
