I decided I was going to put all my attention and focus on finishing it this time, so when Sierra handed me the quest, I duly obliged (after negotiating the schematics for the Nuka Grenade). I really enjoyed it, discovered many new places, which earned me the Explorer achievement. I must have leveled up 3 or 4 times as well, which was pretty good going for just one quest.
Now I know that there is no better way to test yourself in the wasteland than by just going out there and exploring, but trying to find all them shiny bottles of Quantum, in all their scattered and various locations, taking on a host of enemies for each one, was ultimately the hardest tester I've had to date out there in the wasteland, especially considering I'm a level 20 and Deathclaws and giant rad-scorpions are as common as Mole-rats and Bloatflys at that stage.
Anywho I just wanted to put a post out there and tell everyone about one of my Fallout stories, Happy hunting folks!
