From the publisher:
Indomitable Gauls is a simple tabletop RPG inspired chiefly by the Asterix comics.
It's good for adventuring in the ancient Roman empire and thereabouts but also for playing existing fantasy RPG scenarios in a family-friendly way. And for playing with adults who just want a bit less violence too.
In the past I've enjoyed running traditional RPG adventures -- 'traditional' in the sense that lethal violence is on the table -- with the fights recast as unarmed martial arts, and that works well but requires the GM to evaluate each and every sword- or laser-armed encounter.
But in the style of 20th-century Franco-Belgian comics about plucky Gauls, you don't need to do that. The Romans are still coming at our heroes armed with their full array of pīla, gladiī and so forth, yet as the Gauls CRASH and PAF their way through the ranks of legionaries, there is little malice or menace. Even when you're tied up and about to be fed to the lions.
Adventures tend to be short in Indomitable Gauls, as you're rolling your Pages die (equivalent to Cthulhu Dark's Insight, here representing how many pages are left in the album) for the whole group rather than an individual player character. If you feel like you've not played for long enough when you finish, begin a new adventure!
