I'm sorry but I don't see one mobile game that brings me any interest compared to console games. Not one.
I personally enjoyed Puzzle & Dragons and Monster Strike.
But those aren't anywhere close to console and PC gaming, regarding a game having "depth", so mobile gaming would never replace the enjoyment of PC/console gaming for me.
For example, imagine MGSV's gameplay. It uses all the buttons and stuff on the controller and lets you do so many things. Same for some other games.
You can't make those type of games on a touch screen.
And especially when it comes to action games, displaying buttons and a d-pad on a touch screen isn't gonna work, thus you can't implement various controls.
I've tried it with Square Enix's Seiken Densetsu remake on mobile and also every sequel of Metal Slug. It was just a horrible experience.
But I do also wonder, if consoles/handhelds were to disappear, I wonder how Nintendo would release a Mario game on a touch screen without a physical d-pad and buttons.
Because I have slight hope that they'll come up with a genius way to over come this.
