I never got into fighting games like Mortal Kombat or Soulcalibur because of the enormous list of combos and my failure to remember them all or execute special attacks properly. But I've been competent with melee character action games like DMC4 and Ninja Gaiden Sigma. The former has one button interspersed with pauses for MOST of its attacks and in the latter I abused the heck out of the Izuna Drop and instantaneous Ultimate Attacks.
It's been a while since I've played a melee character action game and the combo list in MGR is huge. How do you remember them? All of them? Some of them? Some of the special moves require enemies on screen to practice (like the HF Blade energy wave). Couple this with the fact that the special weapons have their own separate list. I only have the pole-arm right now but that combo list is daunting.
BTW, I remember some reviewer saying that the special weapons don't work well with the HF Blade which isn't true in my eyes in what I've seen of the pole-arm at least.
