I also love the drastic differences in the armor and weapon styles. Gives great light to how vastly opposing the forces are; one more sleek and streamlined, almost futuristic, the other slightly archaic and very elegant.
I played RF a long time ago...before it was a free-to-play. I could recognize the game the characters are from by the armor ^^ I had an awesome Bellato. Really a nice piece of art to tempt me into playing that game again
