It really does seem like that. Not only guilds, but nearly every quest is given to you automatically.
this whole issue of multiple roleplay charaters vs one playthrough is very interesting, to me.
like many, i previously thought specialized rp with multiple playthroughs was the best. i do think skyrim does a great job of providing good rp characters, but, the CONTENT of the game is so generic and repetative that those subsequent characters are all cookie-cutter games of previous ones. only my combat approach is in any way actually different. skyrim got boring after about 200 hours rather than playing all the others and the 2 fallouts for 1000's of hours.
recently, after talking with others and doing some reading, i realize that skyrim is, for me, best played with one all-powerful hybrid that can do all the quest/guilds on one playthrough and with the skills to play all 3 styles or any combo during EVERY gaming session.
i now leave my strict roleplaying to the DiD games.
