Well I didn't have any real prior knowledge of all things Gladiator until I decided to make this game. This site has been my friend ever since, and contains damn near all of the information I think I'm gonna need to finish this game. But this site really only has the more famous Gladiators listed on it, and so I don't personally know too many of the lesser known Gladiators yet...
That would be something I have to look into.
Anyway, this is the site:
http://www.roman-colosseum.info/index.htmEdit:What I was basically planning on doing, since I'm focusing mainly on Capua, Ravenna, and Pompeii (short of Rome); is do some research on some of the famous Gladiators that emerged from those three locations and have you tackle them one by one at set points in the game on their home grounds. After you prove yourself worthy by doing such, you will be accepted to fight in the Colosseum, where you meet the big names.
So, you have to become the champion of Capua. That is the first goal on your list. Then, to Ravenna to compete and conquer their champion. Finally, you can fight in Rome, but only after then conquering the champion in Pompeii (Capua's long time rival Ludus).
