I see mobile games as the natural evolution of flash games from the old days. I used to spend my time playing those games and I had fun, but I would never insist on them being the best experience I've ever had in gaming. They were just cute games to spend some time on. To use your examples, Minigore is just like Boxhead. It may be fun but there's nothing "genius" or ground-breaking about it.

In the end, gaming is just an experience, and our emotional attachment to it decides our rating. I hardly care about Call of Duty, but the people who spent their childhood playing online with friends rate it as one of their best/most formative gaming experiences. Surprise, people's opinions on things are subjective.

By the way, as you're the same guy who dunked on Uncharted, The last of us, God of war and Witcher for being games that rely too much on story exposition and have too little gameplay, you seem to have a preference for games with zero/near zero story and offer immediate gratification via gameplay. That's also a characteristic that lots of mobile games share, so that may shape your preference as well.

Personally, I rate mobile games very low because I hate their monetization and I despise touch controls.
