BlueStacks what the heck is it, and why do you need it? BlueStacks is an emulator that allows you to play Android games on your PC or Mac rather than your phone. If your first thought after hearing that was, Why on Earth would I need to do that? then I ask you, good reader, to hold thine horses and consider the possibilities.
There are actually many good reasons that you may want or need to emulate mobile games! You might want to play your games on a larger screen, have greater flexibility with mapping custom controls, or maybe you cracked your phone screen and have been cutting your thumbs to shreds every time you try to play GRID Autosport. Your phone might even just be getting a little old and can t handle the kind of performance needed to run newer games at their ideal specs anymore.
