Zero regrets. Purchased at launch and have had a good time with it. Ive played exclusives and some multi pats on it depending on the game.
Note: I own a gaming pc, ps4, and wiiu. I use them all a fair amount with the exception of the wiiu (just for nintendo exclusives). I play most multi plats on ps4, and have recently played more pc games since they look better with my 980ti.
Edit: some of my favorites are sunset overdrive, dead rising 3, halo MCC, HALO 5, Gears ultimate, titanfall, rise of tomb raider, quantum break, and rare replay (and i know some are on pc). Totally worth the purchase for me.
