Beautiful, but difficult...
Dead or Alive 4 is certainly the most stunning-looking fighter to come out so far. The levels are huge and packed with detailed and interactive objects. I love all the characters, especially Nicole. The online interface is excellent, with unique lobbies and avatars and easy spectating during matches. My only complaints are the single-player game can be insanely hard (especially in Time Trial), and the counter system is very difficult and annoying. Still, if you like 3D fighters, this is a good choice.
