I am amused. At how nobody whatsoever from the Caesar's Legion-loving camp is popping up to say how they'd be making a beeline for the legion fort to volunteer to be a skirt-wearing, machete-weilding, NCR-machinegun-charging cannonfodder recruit? Where's the loyalty, boys??
Hehe. All fine and dandy when yer sitting behind your computer warping philosophy to claim how grand and wonderful and altruistic it would be to be Legion... yet when the rubber hits the road, and you face the thought of actually having to BE one of those crazy kilted asshats, without any magical 'courier' superpowers, and with a machete and the Legate standing behind you saying charge those fortifications or die... ayeah. Quite another story.
That's when the low, mean, viscious and extremely undesireable reality of life in the Legion would hit home. "Um, I don't want to be a legion soldier..." Sorry, it's that, or slavery, or death. Choose now, please. "Um, I've been fighting now for years, I think I'll muster out of the legion now and go raise beans or be a layabout..." Sorry, the only retirement plan the Legion has, is death. Carry on...
If it was your real-life ass on the line, you'd all be running screaming to Vegas, California, or some other decidedly UN-Legion part of the west. Mwuhahahahahahaaaa!!!
The thing is, most legion are integrated unwillingly. To be honest, it would be hard to approach the Legion. How do you join those such as the Legion? Join a tribe and wait for it to be integrated? The point for the Legion is not that we want to be them. We just think there way of life will make humanity stronger if that makes any sense.
