Return of the Forest new good and funny outfits, and Jacky and Ein awesome realized (by a graphic pov): just with the additions that TN implemented so far, DoA5U seems to appeare like a more than worthy remake
Ein has a slightlydifferent face to Hayate's. That or my mind is playing tricks on me.
Also to me seems to be more young, but actually he has always gave me this impression (that the face of hayate and Ein were different) also in DoA3
For VF, we're gonna have to have one of those full fenced ones, because implementing a ring out system will not work for DOA. Or they could make it that you can fight on the ring out part.
I admit that I found the stages of Doa infinitely better in comparison to the ones of VF, so I wouldn't miss the lack of them. Anyway TN could also decide to expand its crossover idea also to one stage of them (but essentially this would say to create a stage without cliffhange, multi tier level and perfectly circular or squared, not really so attractive IMO).
EDIT: fixed some typhos, sorry
