dirtbag: Thanks for the compliment, but you shouldn't worry about the polycount, even with 30 or so legionaries, praetorians and centurions on-screen wielding various Gladii and Spathae, plus their enemies, the FPS never fell below around 30-40, even on my dying Radeon 9600 (Or it was 30 Romans before we came across some Darkies, but oh was it awesome to see those Knights get cut down by a hail of Pila).
okiN: Well, I'll admit, the most I know of is the equipment of the Legionaries and Auxilia, beyond that, not much else, and what I do know of the Gallic warriors is probably wrong. If someone wants to be my historical advisor on the Guals, hell yeah I'll go all out.
Henderson: I'm not familiar with Eagle's Roman mod, (Truthfully, I only checked the forums by chance and saw people were making models and started making em myself). But from what okiN said, they probably wouldn't fit in since they are meant to be 100% accurate.
Raz: I'm usin Milkshape, but check the 'Unofficial Editors' forum if you haven't already and check the stickies in it.
I've gotten the Clipeus in-game now too, its an ugly beast but it gets the job done, it uses the paintjob and backbracing from my Scutum.
