I think this is a great game and thought it my duty to balance out some of the unjustified negative reviews posted for DOA4. I will particularly highlight the review made by Mr. D. Kelly, as whilst i'm normally very tolerant of other people's opinions, i would have to argue that your view on this game is just entirely wrong.
For one thing i have played the worst fighting game in the world and it is robopit 2, not this game. Secondly the DOA series has never been about revising excessive combos, it has been about timing your attacks and blocks to decimate your opponents defense and offense. Unfortunately this requires skill, something that you clearly are lacking.
Next up are the women of the dead or alive universe. I will agree that there bodily proportions are rather extreme and even though i have never been one to shy away from attractive women, i would argue that the rather "bouncy" physics on the girls has a certain comical edge to it. If this was all there was to DOA then i'd criticise till the cows came home (thus why i always complain about DOA extreme beach volleyball), but in the case of the main DOA fighting games you get a great fighting game plus some nice birds, so stop complaining! Plus they're ninja's! Which is awesome!
I'm also sick of people saying that you can't block. Use your heads people! see that blue button your controller. The one with the x on it. Well x marks the spot in this case as, whilst this is called the "free" button in the manual and serves to start a counter when pressed with a directional button, it also acts as your block button when held on its own. Of course this doesn't work if your opponent makes a low attack or grab, which is probably what happened to you Mr. D. Kelly, but you just couldn't believe someone was skillful enough to break your guard so you, very typically, blame the game for your own shortcomings as a human being.
Last bot not least, in terms of difficulty, i love the learning curve on this game. It actually provides a challenge unlike a lot of titles, and of course it doesn't give you a tutorial on counter moves. Have you ever played a fighting game that has tutorials? That's what the manual is there for, so read it before you start complaining. The only reason this game doesn't get five stars from me is due to the slightly limited single player. As once you've done all the story modes, it's only the multiplayer that will keep you coming back. Still a fantastic title regardless and it's a shame there won't be a DOA5...
