First off, I know it’s a game and so on. But I think “looks natural” is also important.
So, one handed weapons that has a horizontal or close to horizontal swings: It better be start from the left side. If you can’t believe, try it with heavy and long enough stuff (at least 500 g). Horizontal swing is way more easier and feels more comfortable when it’s starts from your left side. Well, it would a right side if you are a left-hander.
- Or swing like a Elven Spear and Shield’s sweep: Which is hitting with the back edge. So, it is should be a double edged weapon.
Now, two handed weapons: I would say the Elven Great Sword has a best animations in 1st person view. In 3rd person; Kruber’s Great Hammer’s heavies, and 1st and 2nd light of the Glave.
