I haven't had many console time in my life. I have spent my most time on my PC games. But I love PlayStation 4 just because of all the exclusives it has. PlayStation's exclusives are the only reason why i have stuck to it.
I mean the developers like Naughty Dog and the games that those guys make you just can;t resist them and that's why I would always go with PS4. On a side note, I would really love if the nest PlayStation is backwards compatible. I know with PS3 it was difficult due to the main difference of architecture in PS3 and PS4. But according to the rumours, the PS5 is supposed to come with the same x86 architecture as PS4. So, maybe Sony would surprise us.
