Dead or Alive 4....
I was an SS rank in DoA Ultimate, not exactly special but still, I didn't suck at the game. I get DoA4 and first go to story mode to unlock some costumes etc. The first thing I noticed is about round 5 the AI was getting 12 hit combo's on me that was taking half my health away from me in a couple seconds. I go the options menu to see if I had accidentally changed the difficulty to very hard. Nope, it was still on "normal" the easiest difficulty in the game.
I get a couple costume unlocks from characters I was already used to, and having already looked at the achievements, I knew I would have to complete the story campaign for ever character multiple times to go get all costumes for an achievement.
I started playing Kasumi's campaign struggled through the story a couple times. (It's only 8 round for each campaign.) And then, I noticed that Kasumi and all the other female characters in the game had 6-12 costumes per character (Half the cast is female.) I detest playing the female characters because they are clunky, over used, cheap, and weak to boot.
I still have not this achievement in the 4 years I have gotten the game.
(Seriously fuck the Kasumi clone at the end, and the developers with a 12ft rusty spear.)
