DOA 2 was great, DOA 3 was bit more of the same but still great, DOA 4 was more of the same but okayish, DOA 5 the DLC ruined it for me, DOA 6 seems to be more of the same probably not going to review well.
no tag battle and pay to get more in the game. I don't understand why someone would buy it when they announced a free to play version coming aswell.
