Two separate games. It works and plays like a FG. It should be taken seriously regardless if people are allergic to seeing bikini's and breasts as if they've never watched porn before. Every fighting game has fan service...
Not necessarily, but DOAXBV definitely did no favours to DOA's reputation. DOA's always been a stigmatized franchise from the start. However, I find it odd that DOA3 sold over 1.5 Million units whereas every other DOA game after it (including DOAXBV) sold less than 400,000 units. DOA3 was probably the closest to a DOA game being taken 'seriously' (apart from maybe DOA5LR to an extent).
