The CE is much bigger than I expected!

How does this game play compared to the older ones? There's a new director and the new Ninja Gaiden game sucked so I'm kind of wary. It seems like they didn't change anything then? Always seemed like kind of a pointless sequel, and with TTT2 just out I'm not in any real rush to pick up another fighter.
It feels very similar to DOA4, but plays a bit slower. This may be due to the added frames of animation. The biggest noticeable game play additions are the power blow system (basically the DOA equivalent of a super move) and the revised side-step system...as in you can actually side-step now, although it's kind of slow.
I wouldn't call the game a pointless sequel...it's been almost seven years since DOA4 came out on 360 and
11 years since a DOA fighting game was on the Playstation platform. Even with its problems, the online play is better than DOA4's. Plus you have lots of new moves, a much better art style, and the typical array of balance changes. Rig and Mila don't do much for me as new characters, however, and the added VF characters just feels lazy to me. I would have preferred to have seen three new characters in their places.
Also you have to actually unlock stuff the old-school way- Akira, Sarah, and Pai must be unlocked by playing through the story mode and/or obtaining a certain number of titles. Ditto for the playable boss. Outfits also have to be unlocked. Almost all of them can be obtained by beating the arcade mode multiple times with each character, but at least three of the females (Tina, Lisa, and Christie) have "legendary" swimsuit outfits that have to be earned by clearing some of the modes of the legendary difficulty. You have to unlock master difficulty before legendary becomes available, too. I tried the hardest difficulty available and by stage four was getting destroyed by the CPU. It countered fucking EVERYTHING.

But yeah, right now I think TTT2 is the better game. It just offers way, way more content and the roster depth is unmatched by any other 3D fighting game. TTT2's online play is also far better and easily up there with Arc System Works' games as the best netcode available in any fighting game.
DOA5 also has zero customization options available and feels outdated in that regard.
