Hail Caesar Rules by Warlord Games.
My Caesars Gallic War Book Library
Adler Miniatures do both Marion/Caesarean Romans and Gauls I bought sample bags of both Romans and Gauls however I was not impressed with the cast quality. The swords are extremely fragile on the Gallic figures. They also produce some transfers for both the Romans and the Gauls. I bought one lot of Gallic Shield transfers I thought these were expensive but they are very nice.

Magister Militum Gauls and Germans.
Newline Design produce some fantastic looking Gauls which I have mixed with Pendrakens Gallic range. Newline also have other ranges which would be suitable for the Roman auxiliaries.
