Conclusion: I haven't got my game in yet, but I have been one heck of a DOA player when I first started the PS2 version. This game has brought me back to the fighting style games since I stopped with street fighter 2. So far I have not been disappointed, and I know I won't be now.
Summary: A couple of years on from DOA3, you're probably expecting radical changes since DOA3 was graphically awesome... well, withdraw those expectations. Firstly this is NOT DOA4! This is DOA2 Ultimate. The graphics are not different from DOA3 and characters remain pretty much the same.
