Yea they are pretty solid for XP & getting all your companion perks. That's at least what I've been using them for. Seems like I've reached the ceiling for the minutemen radiant quests because they keep sending me to the same farms for the same stuff. I'd like to start using another faction to start exploring new places. Any suggestions? I don't even know if I've gotten into the RR radiant quests yet? I completed all of Tinker Tom's Mila placements, and a few dead drop quests from the doctor in there, and he hasn't given me anything else. So far PAM has only sent me on one quest to retrieve a password. Other than that, its been all Desmonda quests which are the main storyline. I barely spend time in the Institute so I don't even know who to talk with to get more quests outside of Shaun.I think so, that's where I'm at. And the Brotherhood's point of no return quest is "Tactical Thinking" I think.
All those Minutemen and Scribe quests are called "radiant quests". They never run out, they will always replenish. I really only use it for the XP.
But it only looks like I have maybe 50-60% of the map explored.
