First, this runs off LTE so you're paying for the amount of data you use. So it all depends if you want to keep on paying for LTE usage instead of using your home/office wifi. Speedwise, it all depends on the game. It's better for simulation games like starcraft and such. Not so good with FPS games where that microsecond drop in speed will be life and death. Forget about live streaming, will use too much data and will be slow.
