As far as Modes, this game has every feature that Dead or Alive 5 had, namely: Story Mode(Which is silly and presented in a disjointed and confusing way, not worth it), Fight(It consists in Versus, Arcade Mode, Time Attack, Survival and Team Battle any can be played in both Single Player and Multiplayer variety) and Training(Tutorial, Normal Training Mode and Command Training, in which you are to complete a character's movelist). The only new Mode is Combo Challenge, where each character has a set number of combos that you are to clear. There's a decent amount, but there's not a whole lot to it. There's also a really neat feature called "Exhibition Mode" that unlocks every costume for Multiplayer play, but disables stat tracking and trophies, pretty neat if you take the game to a friend's.
The game adds a total of 5 new characters: Leon, who was considered a Bayman clone by many and probably the reason it was missing in the first place, Ein, often times considered a Hitomi clone(Although Ein came before, and they are not that similar) and is Hayate with a different Moveset, Jacky from Virtua Fighter and Momiji and Rachel from Ninja Gaiden. The new characters come with new movesets, and everyone but Bayman is quite fun to use. Some may want to count Ein among the "Bland new movesets", since he shares moves with Hitomi and Hayate, but he was my favorite character from the DoA series, so I can't complain. Momiji, Rachel and Jacky have totally unique movesets and they are very fun to use, specially Momiji with all of her aerial attacks.
Is Dead or Alive 5 Ultimate worth it? If you don't own Dead or Alive 5, very much so. As stupid as the sexual pandering is, Dead or Alive is a very easy to pick up and play game, you can just mash buttons and make stuff happen, and if you delve deeper you can find actual depth. And hey, now you can turn off the breasts jiggling, it's a start! If you own DoA 5, however, it's a harder sell. The new movesets are pretty fun, and at least 3 of them are very different from the rest of the cast, and quite fun to use, but there's not enough new content to justify buying it again if you don't really care about fighting games. All in all, Dead or Alive 5 Ultimate is what Dead or Alive 5 should've been from the start, but there's no real incentive to buy the same game again.
