I played DOA4 years ago and was really good at it(no joke). But the game got old and i never liked it(DOA3>>>DOA4) and i don´t plan on going back to this... old game.
But i played DOAD a bit some days ago. Even if it´s almost DOA4.2, i still liked it... a bit.
I enjoy the game but its like a stripped down version of DOA4 with minor tweaks. I wrote a review for a gaming site with more detail about my thoughts. I'll post a link when it's approved.
