Hello ! I'm new to Fallout 3 ... (I'm coming from Skyrim) Anyway, I would like to know if doing the Survival Guide sidequest of Moira is the best way to go for a Newbie to gain XP and basically learn the ropes and landscape of the game? I am right now at the "Following His Footsteps" quest and I'd like to switch to this side quest... Thanks!

Yes, The Wasteland Survival Guide Quests can be useful.

Any Mistakes made can be fixed or done differently on Your next characters, but...
