Well that's my problem, seeing Gallia as a whole new system. I don't want a whole new system - the one we've got is plenty enough, thank you very much - and because of the Gallia's "whacky factor" I've only been there once, in SP, and will most likely never go back there again. It's like stumbling into another mod and I find myself asking, what's the point?
Of course, Gallia's mostly done already so I'm just pontificating here. If you want to play in Gallia, all the more power to ya.
