Who's to say that the people of Nirn even have bodily functions in such ways? There are no toilets, the food offers various forms of benefits, such as increased health and things like that. Who's to say that any of the food becomes waste at all? Maybe it's ALL turned into energy/magicka/etc.
I'd say, if anything, it's
unrealistic to include these things.
Am I the only one who starts to develop an aversion towards the word "immersion?" Some people are better off playing The Sims instead of TES methinks....
It's a good word, it is unfortunately used synonymously with "realistic" sometimes. Immersion just means the ability to get involved and "lose yourself" inside of the game. To really believe you're part of the working universe of the Elder Scrolls. It does not necessarily mean realistic in the least bit.
