that dw engine is perfect for the game
almost no clipping, in 5 if you pause the game you can see hand get through body, costume clipping though body
in 6 clipping almost non existant
if you notice tekken 7 share the same story beat as all it's previous installment and tekken 8 might be the same again
at least you've sense some storyline progressing between doa5 and 6
