I am big fan of gladiator games, going back to Gladiator by Avalon Hill. I have tried all sorts of rules systems for gladiator combat, and have a good collection of gladiators from Foundry and Westwind. I have an arena for my miniatures to fight in. I have playtested other types of rules and reported my findings.
Besides, it will help justify the fact that I took Latin in school instead of Spanish...
