Dark Souls hands down.

I've never paid more than $60 on a PS4 game.

If I'm not mistaken Resogun is still available for free on the PS Store. That game is ridiculously addicting.

Grand Theft Auto V. Or Borderlands 2.

No issues with it. I put a pair of the sticky thumbs on the joysticks and it's been great.The only downside is the battery life..
