I'm not sure if I qualify as a ruleset reviewer, except for the fact that I've had a lifelong interest in gladiators.
Thirty odd years ago (yes, I'm that old), I got fascinated by the concept of gladiators, from the Etruscan/Samnite funeral rites to the better known arena "sporting events."
Started collecting reference material, and the same amount of years later I have an extensive database and library on the matter.
So I suppose my main contribution will probably be historical backgrounds and info on gladiator types, etc.
We tried to run a gladiatorial campaign at our club using the rules from (who else?) Gladiator Games but they turned out to be just a bit too detailed. Some combats lasted too long, and the non-playing participants had to wait too long before it was their turn. So if this ruleset promises shorter combat sessions, but without a complete sacrifice of historical detail, I'm very interested in trying them out.
So bring on the Murmillo's, Dimacheirii, Thrax and Secutors. We'll give them a thorough workout!
