Control is tight, but still no calibration option, definitely need that to be updated. Graphics great no complains at all. Sound is a bit low on the fidelity can hear the snap crackle pop like an FM recording, remember the sound quality when God of War first came out? yeah like that, so need that to be fixed too. Overall, totally worth a buck!
