My wife is playing Dragon Age: Inquisition right now on the 360 and she is having all those problems with it being glitchy too. We just bought a PS4 online with part of our tax return (still waiting for it to arrive) but she plans to trade in the 360 version after she finishes it and get it on the PS4.
I am envious of your copies of DQIV and V. I only have VI and the other two tend to be kind of expensive now.
