Fallout RPG, using sr4 for a fallout rpg Options

[Drace]

Hey, haven't played or posted on here in years, but dusted off my copy of the sr4 rulebook I got, and picked up most of the core books at discount when my local store went out of business.

Anyways, now that I am done blabbing on about nothing, a few friends and me had an idea to play a fallout based rpg since both of them had recently gotten a copy of fallout 3 and finished it. Since I am the only person in the group to know the majority of the rules, let alone to have played all 3 of the games and know the most fluff, I have been given the job of being the gm of the game.

I am looking for any ideas as to how to run the game? Should I let them do what they want, have certain npc's give them jobs like shadowruns, let them go hunting, start a gang/town etc? Any advice would be great as I have a few ideas, but it looks like they may be exhausted out pretty fast depending on what they want to do.
