Ok fine, Sony used to do BC up until the PS3, but stopped doing it with PS4 and decided to double dip on gamers, forcing them to re-buy remakes meanwhile the PS4 was perfectly capably of playing PS2 titles. MS continued with BC and now after Sony has seen all the positive feedback MS has received over it, and the negative feedback after hackers found that BC capabilities were possible all along, they backtracked on their original statement that a new console is for new games and thanks to MS, now going back to putting in the effort of adding BC.
Better?
