Dead or Alive 5 actually has one of the best tutorials in any fighting game I've ever played. There is actually a sliver trophy for completing all of it because some of the later lessons cover some really complex concepts. Its really really in depth.
Agreed. A sound and fun game probally doubly so for those fans of the source material but in the end I thought the combat was lacking. And its incredibly frustrating as an action game fan (my favorite game of all time being Ninja Gaiden Black) to see this style of combat so widely adopted across multiple games now as almost some sort of combat engine middleware.
