What game(s) did you get for the PS4?
Try tomb Raider at 60fps it's amazing!... I tried the Strider demo, don't know if that's your thing, but it reminded me enough of a polished version of the original (but now you can reverse your flips mid air, impressive feat), so I may get it.
and well, this month's free game on PS+ is Outlast, I think you can still get Resogun for free as well, very much worth the yearly fees (however that along with xbl gold... it's a lot of recurring cost to take full advantage of two consoles... if I was into getting an xb1 I would consider I had no choice but to get it as the box barely boot without it).
