Don't sweat it if you really can't get to grips with the system. The regular turn-based, skill-choosing combat style will also be available if you prefer.
Oh cool, so we'll still be able to use the systems from the original? Edit for clarity: I'm more specifically referring to the grapple system - I drastically prefer the old version to the new version.
Yes, there'll be a form of grapple combat similar to the old one, which we're now calling "Struggle" combat since you're being lewded by enemies and fighting to get free.
