A multiplayer sword game?

I'm not sure about "a lot" of people, but there is a game called Monster Hunter (PSP, Wii, PS2) where you and up to 3 other hunters can fight the same monster. Your arsenal is COMPLETELY customizable from speed to attack to abilities to ranged etc. here's a video: http://www.youtube.com/watch?v=7D6jMRuqekU it isn't "medieval" but it doesn't have any present day technology. Oh, and you need to love cats!
