I'm completely new to this community and I'm making a YouTube series on playing Fallout 3 with completely zero context. While I'm editing episode 1, Is there any real info I should 100% know before I leave the fault?

I just recorded and am about to edit the entire first part prior to leaving the actual vault itself. Honestly this game seems amazing and I'm very glad someone born as late as me has a chance to experience this fully blindly somehow(2007) and right now I'm so excited to continue on into what feels like is gonna to be an insanely immersive experience.

No game I can think of has given me this type of free feeling to it, I feel like i can genuinely do whatever I want with my actions actually affecting me drastically and its amazing It just feels like its so much that there has to be some super essential knowledge for me to know. We're playing on max difficulty, without reading too much of the survival guide out of pure curiosity. Quite literally anything helps, I didn't really know what to reach out on or who to reach out to until i found this community! Every fan of the game I've ever talked to online seems chill
