I can only speak for myself when I say I have been underwhelmed by the PS4's lineup. I purchased both a PS4 and X1 at launch for one reason, to enjoy next gen AAA exclusives that each console has to offer. I had some fun with Killzone Shadowfall at launch and more recently Driveclub but other than that my PS4 hasn't had much use when it comes to exclusives.
It's easy to produce lists of games, but of those games, how many are worthy of being called 'next gen', that is why I invested in a PS4 day one, to play games that were only possible on the PS4 both in terms of power vs. PS3 and exclusivity to that platform.
I am not playing the whole 'ps4 has no games'card because that obviously isn't true. But for me, in my personal opinion, for my personal taste, the exclusive lineup is lacking in content. Thankfully I have games like Uncharted 4 to look forward to but I still desire a little more. You can never have too many great games!
