All The Legion Side Quests:
Cold, Cold Heart
I Hear You Knocking
The Finger of Suspicion
We Are Legion
And let's be honest, to all of us who have done these 4 side quests, the ONLY one actually worth mentioning is the "We Are Legion" one.
Let's look at all the NCR side quests:
Anywhere I Wander
Back in Your Own Backyard
Bitter Springs Infimary Blues
Boulder City Showdown
Can You Find it in Your Heart
Climb Ev'ry Mountain
Eye for an Eye
Flags of Our Foul-Ups
Hard Luck Blues
I Don't Hurt Anymore
I Put a Spell on You
Keep Your Eyes on the Prize
Medical Mystery
No, Not Much
Restoring Hope
Return to Sender
That Lucky Old Sun
The Coyotes
The White Wash
There Stands the Grass
Three-Card Bounty
We Will All Go Together
Quite a difference, don't you think? I am perfectly aware that some of these NCR quests can be sabotaged in Legion favor
My other example would be companions. There is not a single Legion companion (Or Pro-Legion companion) in the game; but on the other side there is Boone, who is NCR through and through and will shoot Legion soldiers on mere sight. Then there is Gannon who will not even join you if your Legion reputation is too high.
When you consider that NCR and Caesar's Legion are the 2 competing main factions in the game, this is hardly fair. While I may come off as some moronic Legion fan, this is really just something I've been pondering for a while.
I also wanna point out that this has absolutely nothing to with the main story.
