As you can read the heading the Nox App player is good for playing android games and etc. It is very easy to use, I have been using this app player from last 6 months and I liked it very much for me it seems to be the best android simulator.
Trust me if you phones battery gets downs easily and you need to play some games as much as you can, you may go for Nox App Player, you can install any android app in it.
