If this has been discussed before already, just ignore this post.
Up to now I haven\'t seen any double handed weapons in the game. Even battleaxes and longswords are used single-handed.
If there would be strong weapons blocking both hands, that would be more realistic and more fun, because the people would have to decide between two weaker weapons and one strong.
You could also limit this on the weaker races, so there would be some races that still can handle two of them, maybe with some punishment in damage, accuracy or speed.
Just an idea ...
