First, I'll say that I have FCOM installed, so I realize the game is harder than vanilla. I don't mind more difficulty/trickiness, but my character doesn't really have anything to do at the start. My journal is full of quests that are waay too hard for me at this point. I don't really have a way to progress to get to the level where I can take those on.
The only quest I did complete was Thoronir's ill-gotten wares, although I had to cheat a little to defeat the enemy when I was Lv 1.
As it is, I can only take on 1 humanoid enemy at a time, backing up the whole time and using at least one potion per fight. I've been grinding with rats and crabs and trying to lure a bandit away from the pack, but it seems like I'm just spinning my wheels and there's got to be some actual questing to do at the beginning.
I have delayed the main quest because as an RPG vet, I've learned that the "urgent" main quest should always be done after all possible sidequests. If that's wrong in this case, please let me know.
