Attack on Titan 2 is definitely a vast improvement over the first title. It's slicker, faster and more engaging.
Ni no Kuni II is easily one of the best RPGs on the PS4 and PC. A masterpiece that needs to be played by everyone.
Warhammer: Vermintide 2 is everything that the first game so good while addressing the issues that frustrated fans of the first title.
Dare I say it...Dynasty Warriors 9 might be the single worst Dynasty Warriors game that I have ever played. It's vastly uninspiring, boring and repetitive. If it ain't broke, don't fix it.
