First off, I'm a huge fighting game fan (even if I'm not any good at them) and while my preference is for arcade-style games, I had a lot of fun with Soul Calibur 2 on PS2, Xbox and GC (I had a fierce rivalry with my friend which eventually came to a head with a four hour, ring-out only, mega-match to determine the best player. It was hell-of fun.) and I adore DOA:D on my 3DS.
My problem lies with how technical the game is; DOA4's difficulty is way too intense for me to learn any of the basics to a degree I can feel confident using them, but the 3DS game has a nice curve, is a little bit easier to start and I've ended up being a fairly competent, and more importantly confident, Kasumi/Ayane player although I have most of the costumes available to everyone.
What I'm asking then is; did they take lessons from the 3DS game with regards to how approachable the game is or does it still demand a high bar of technical proficiency right from the off.
