Edit: talked a lot about NG4 and DOAX3, said that another DOA spinoff would be nice, less Warriors from KT, RPGs would be nice.
Graphics are good but disappointing at the same time (great character models &1080p, but no AA & old textures). Sound is excellent. Stage design is okay, they should do like before, more interactivity, ceilings, verticality, etc.
Character design is excellent, but there should be as much for males and females, and more "interactions" (quotes, etc). Balance and game are overall good.
Need more updates on Steam version, share japanese links like Team Ninja does on their twitter. Don't listen too much to criticism when it's just "I don't like it!", but listen to what fanbases are saying (Ninja Gaiden), while still deciding on your own. Slower DLC release schedule, and more casual costumes, less bikinis (put them in DOAX3).
