Seriously- Next tes game i want REPLAY value because i Can't join all guilds at once! Or at least several. Maybe some radiant quests might pop up that go against another guild if you have to many?
First off - the TES games don't
need "replay value", when you can play
one game for years. Also, the new leveling system adds plenty of replay value - TES isn't about the game world, it's about
your character. I do not "Roleplay" in the sense of "Make [censored] up and say what's happening isn't what's actually happening", though I do "read between the lines" of context in the series to derive extra depth. Having all the guilds joinable keeps options
open - I can
Always choose "Not" to do a quest, and it doesn't stop the development of my character's story.
I'm not even going to use Race+six to distinguish my characters (They're all female Khajiit), but my neither my Berzerker nor Warrior have need to join the DB, and while she did become Archmage of the College of Winterhold, that's because the psijiics are dikes and you're not allowed to argue with those [censored] elves, not because she's a competent mage. In fact, I highly suspect that it's a Psijiic ploy to keep the College of Winterhold weak, especially after they stole an artifact that the artifact went through great lengths to recover. [censored] elves, why can't I kill them?
Anyway - likewise, my Sword+Board character's not a mage type (Yet), though she may join the college as an associate at some point in her future. However, she's
far more interested in helping the Legion reunite Skyrim, and just exploring the game.
Guilds make up less than 10% of the Quest Content of
Skyrim, and Quests are less than 10% of the
Skyrim experience. I don't care about the "Big Stuff" that I become famous for - I saved a Farmer from a foolish death at the hands of a giant, I've had to settle stolen-item disputes. I've stepped into dungeons of impressive architecture and depth, without even realizing what I'd stumbled upon.
I also have
no intention of doing the Thieve's Guild quests this time around. In fact,
Skyrim does a MUCH better job with the guilds by actually
making me question the morality of an act.
In Morrowind, Habasi wants a diamond. Getting one for her won't hurt anyone - the Clothier has three, won't mind them missing, and she doesn't have any use for them beyond hiding them in a box anyway. The only point that could have any impact on the player is robbing the Ald'Ruhn Mage's guild... but that's only because they put a paranoid, trigger-happy psychopath as watchdog - And even then they don't notice or mind that he's dead and the place has been cleaned out afterward.
On the other hand, right from the get-go in the Thieves' Guild in Skyrim, you put an innocent man behind bars just because he ticked off a corrupt merchant by running an honest business. The
entire town laments the strength and omnipresence of the guild, and the way your actions affect people is at least heavily
implied - as opposed to "Open for Business as Usual - don't mind the lack of anything of value on the premises" in the Mage's Guild of Ald-Ruhn.
