Only quoting the last one but I’m responding to the entire bit.
From both personal experience and anecdotal evidence from friends who are members of the SCA and one man trained by a professional swordmaster as well as a blacksmith who forged his own two handed blades, I can tell you you do not “dual wield” two handed weapons. They can be used in one hand, yes, if you are willing to basically defeat the entire purpose of using a larger blade, and are equally willing to be less effective than someone wielding a more reasonably sized weapon in one hand (the advantage of a ‘hand and a half’ sword is versatility, at the cost of losing some measure of effectiveness in either). That said, if you believe you can dual wield a large two handed weapon, one in each hand, and fight a horde of monsters too stupid to be intimidated, I can accurately place your chances of doing so successfully somewhere between ghost and snowball in hell.
Dual wielding is not as simple as “pick up second weapon, be twice as good in a fight”. It’s a great deal more complex than that, and it completely changes your combat stance, balancing, positioning, attack options, defensive options, and effective range. You also have to develop an entirely different set of skills than you need for wielding a single blade or hammer, and god help you if your weapons are mismatched or not built with balance in mind. There is a reason that most instances of dual-wielding a person sees depictions of involve shorter blades, and that is because they are smaller and significantly easier to control, and thus there are fewer ways to screw up with overextension.
I cannot honestly say I have the experience of being an eight foot tall freakishly strong monster, as I saw mentioned earlier, attempting to do these things. Perhaps it would be easier. But I have a sneaking suspicion that as the average sword is built to be used by a human range of wielders, an oversized person trying to make up for a lack of balance with extreme strength is probably better off picking up a different weapon entirely, presumably one either sized properly for him or lacking in the “ergonomically designed for normal human hands” department. I’m imagining having your pinky finger slipping around the pommel of a blade mid-swing because your hands are too big for the hilt would be a good way to hurt yourself or throw off your swing.
In short, it’s theoretically possible, but horrifically impractical. And even making it possible or wanting it to be is enough of a corner case that I can’t see code needing to be devoted to the possibility in the first place.
Note, I’m not saying you’re an idiot for suggesting it. Just suggesting that it might be wise to remember that combat styles developed centuries ago and refined for hundreds of years by people who saw actual combat most of their lives are generally remarkably effective. The further you deviate from the “tried and true”, the less likely your chances of success become unless you have had some incredible insight unconsidered by those that came before you. If you have that incredible insight, you can do something new and amazing. Without that insight, you’re retreading ground dismissed as unusable by people with infinitely more experience than you probably have, quite possibly for reasons that you lack the experience to have understood or considered beforehand.
In that light, I submit that “I’m really strong so it should work” is not a heretofore unheard of insight.
