I'd have to agree about the lack of consequences, a new building in the waterfront is all you really get for completing the TG quest line and I can't even remember what happens after the the DB quest. The majority of the quests themselves were fun though, I especially liked the subtle way the DB were introduced, a few rumours, a man put in the dungeons for performing rituals and eventually if you happen to murder an innocent, you get the visit from Lucien.
The Mages Guild had to be the most atrocious quest line, utter derp from start to finish as I recall, though I suppose that resurrect staff you get from Mannimarco was a decent reward, I remember going into dangerous (OOO) dungeons and using it to build little armies of undead, leading them on massive rampages into the deeper areas, good clean chaos.
*edit*
Ouch, looks like the UK is getting shafted, 129 pounds is roughly $212...do I really want a plastic dragon *that* much?
Bugger it, just pre-ordered the standard release for 30 pounds (with release day delivery), plus I get a fancy cloth map, shove your dragon statues up your arse.
