Of course, you're right as always.

I don't, because making games mobile-friendly usually makes them less PC/desktop-friendly, considering the size of the screen, the controls, the power usage etc. While mobile devices can make some pretty good looking games nowadays, they are and probably will remain lagging behind of games made specifically for PCs and consoles, because they have to run with much less power.

PC gamers complain already now that consoles are restricting progress in PC games, and making games less mouse/keyboard friendly (you have to have a gamepad, man! Even if you are playing on a desktop.). I wonder what they will think if most games were restricted by phone and tablet hardware instead? What would The Witcher 3 look and play on current tablets?

You can already see this with some PC games, which are basically ported from mobile versions. Cartoon-style full motion video (like in Baldur's Gate Enhanced, which is made also with tablets in mind and has less impressive videos than even the original old PC-only version) because videos take too much space on mobile devices, icons and objects that look oddly big (because they are designed for smaller tablet screens) etc.

If I want to play my Android games on PC, I guess I can use the freeware Android emulators for that.
