Didn't get into 3 very much. Either time I tried it. Oblivion, I just played with a fairly generic build. Mostly mêlée with a dash of magic for spice. Skyrim was the first Bethesda game I truly played a role with. My character was an Altmer, though I didn't use magic as much as I could have. I loved stealthily shooting arrows at dudes and taking bandit camps by stealth. And I was really into alchemy too. Had a lot of fun mish-mashing loads of random bits (as a compulsive picker of all sorts) into something useful. So I suspect a focus on stealth and whatever helps crafting would be good, as well as confidence for conversations, and a dash of luck. Any other ideas? As a hoarder, I guess... Uh, athleticism would help not overburden me?
