So I've been pretty excited for the Legion since I heard they were going to be in the game, and I absolutely loved what I got from them. But that's the problem, there's almost
nothing to do for the Legion! They have five side-quests: Cold, Cold Heart, We Are Legion, that other one Vulpes Inculta gives, I Put a Spell on You, and I Hear You Knocking. Unless you count the 3 (yes, 3) arena battles and getting the girl her teddy bear back as quests. They also have 3 bases (and a cave) with any named characters, and 1 vendor (the Arizonan trader whom I quite liked). The NCR has a few times this many quests, and many many times more traders and shops, and bases, and just named characters in general. You can even take Nelson for the NCR! If you kill everyone at Forlorn Hope, the Legion just says 'congratulations', and then more NCR spawn there. Also, it felt more like you were just helping the Legion out than actually joining them. You don't get any armor and only a weapon or two from them in the entire game.
I liked the main quest, but the characters of the legion other than Caesar just are not fleshed out at all. Even Vulpes Inculta, advertised to give 'Dark Brotherhood style quests' only has 3 short quests to give.
Is anybody with me on this? I loved the game, but this aspect was just a little saddening. Felt like there was a lot of lost potential.
I wasn't entirely sure where to put this so I decided to play it safe and put it in the spoilers section
