This game is good and many people would like to see some multi-player version but I don't think that it would fit into this story.
I would, however, like to see something like this game as a MMO especially with the fighting style. There are a few kinks in it, but nothing there that I think is too hard for you guys to handle.
A story along the same idea with a few classes and a fun jaunt into history would be amazing.
My two floriens.
