I would truly be sad if the kind of melee combat that is possible only in MB:warband and cRPG were to die out because this one became "too dated" (i'd probably still play it) and no new games were able to keep that same mechanics and experience.
You are right - NO other game has this right now.
MB:Warband and cRPG are easy to learn (left click does this, right click does that)....ALMOST IMPOSSIBLE to master....and thats what makes it so amazing of a game. As new players struggle through the different challenges of swing directions, timing, footwork, feinting, manual blocking, chambering, etc....they slowly see themselves getting better.
It just takes people that can see the the potential and the skill in the system, and put in the diligence and self discipline to get there....which, albeit is not much of the gaming population....but enough.
I really hope neither MB2 or chadz&co sell out on ANYTHING. This melee combat system we have right here in cRPG is TOO unique and great to let die out.
