Yes, mobile games like Asphalt 8, GT Racing 2, and other mobile games usually run faster, and look nicer when played on my Windows 8.1 desktop computer.
Some mobile games like "Clash of Clans" and "Candy Crush Saga" have a lot of fans, so their fans may want to play mobile games on their PC when their smartphone or tablet is charging, off, or when they can't use their mobile for whatever reason like their smartphones are banned at work, or school.
A lot of people also prefer keyboard, and mouse rather than touchscreens because Keyboard and mouse is more accurate, and responsive.
