I can't really imagine there being complicated sewer systems in Skyrim as in Imperial City, as it would seem too "sophisticated" for the people of Skyrim (no offence lol). Also I hate the sewers and there are no real reason for them to be in the game. I don't see any toilets, sinks, drainage systems or anything in TES! There were some fountains inside Vivec and some water pipes thought, but that isn't worth an entire sewer system.
Anyway: What are your views on Sewers? Love em', hate them? Do you WANT them in Skyrim too? The only purpuse a sewer would serve in Skyrim would be a escape route. :facepalm: They are so damn frustrating and you only end up being stuck in them for hours.
PS: Yes I'm aware that I messed up the thread title. :facepalm:
