Played both PS4 games already, but I'm glad other subscribers who haven't get to enjoy them.
Tales from the Borderlands is surprisingly great, with legit great comedy and a charming cast. I say that having never played any of the main Borderlands games, too, so don't worry about the humor being off-putting if you're not a fan.
ABZU left me cold, and I say that with Journey being a personal top 10 game. It looks amazing, don't get me wrong, and there are cool moments, but it tries so hard to be Journey/Flower 2.0 without having any of the innovation or soul that those two games have. If you haven't played Journey and/or Flower, then ABZU will probably be a novel experience worth having.
