Because they surely gave us a lot of DLC male costumes during DOA5 lifespan. But really not only that. It's the re-used content from DOA5, no new mode replacing tag, no Leon, stages are awful, no new character themes, no hairstyle choices for male characters, hair in general, lighting that makes everything looking plastic/PVC etc. I just think this is not worth of 60 euros.
DOA Quest is the new mode though, some males do have different hairstyles Diego and Eliot for example, my character got cut too but I'm not complaining, there hasn't been new character themes since DOA4, everything else is just your opinion.
