Hi,
I had a Nexus Player most of my game don't work on usb stick and it don't have a sd card reader. So, I don't like him very weell for playing game (Kotor, tales's games...).
Now, I want to know if you will have a box offered me but with a maximum budget of CAN $ 100 ($ 75 US). I don't need bluetooth (wired gamepad) and 4K.
You'll have even less success than your Nexus Player with any other "box" don't bother. Invest in the ShieldTV or a game console. Connecting an upper end cellphone running Android over HDMI may be suitable if you already own one.
