I am tempted to return to PS I think. Online gaming isn't a big concern and neither is voice commands that the Xbox boasts. I like the fact that Metal Gear Solid is available on PS4 too. I played the first MGS on PS1 and Sons of Liberty and Snake Eater on PS2.
Lost touch since turning to Xbox so it will be nice to get back into those games. I must say that Mass Effect was a brilliant series on the Xbox though.
