Here we have a more sophisticated arena than mine, but it is flat like mine. It is a felt arena made by Hotz ArtWork. It is a square 58.5 x 58.5cm, with the arena area measuring 21.0 x 21.0 inches/53.5 x 53.5cm in diameter. The hexes are 1.0 inch wide.
Hexes are a constant in gladiator games. The problem is the facing of the fighter and the scarce importance of sophisticated movement in a flat terrain. It is a solution but I think this net can appear too strict, you have a limited space for your moves, and the feel is that of a boardgame. Well, this felt has a lot of hexes, so you can move enough…
