I must admit, this one took me by surprise when it got mentioned but as always I was collared hook, line and sinker :-)
The rules are a play test list by one of the members of LAF and are proving to be much fun (swing on over to have a proper shufty) with never two matches the same.
My Ludus is owned by Bibulus the Flos (a given name...) and is a small arena in the provinces. The basic board is a lasered plate with 30mm across the flats hexes scored on with a gap between them, these are then covered in sand and painted a suitable sand colour.
The sides are bendy MDF and will be enclosed by the rest of the arena, seating etc. I haven't quite decided on the layout yet for the rest but I'd like to include some other elements, like quarters for the gladiators and some rooms for the lanista... We'll see.
