I don't like it when fantasy games try and simulate technological progression. Just look at Fable and how it completely svcked the charm out of those games...
The Dwemer (and possibly the Reguards) are exceptions as far as i'm concerned. The rest of Tamriel should stay medieval-esque. That's why I like the series. If I wanted an RPG with guns instead of swords, i'd find one.
The "charm" of Fable is subjective from person to person. Personally, I thought the clockpunk/steampunk far more exciting, unique, and "charming" than your standard medieval fantasy RPG, which has been done a million times over.
Anyway, that's not my point, I'm not attacking anyone here and I'm not disregarding your own opinion. I'm not even suggesting that modern guns, or other similar technological breakthroughs, should be in the Elder Scrolls games at this time. However, I do think it's very silly to just assume that it can
NEVER exist in the world of Nirn. That's just... well, kind of stupid to put it bluntly. What, another 1000 years is going to go by without any advancement through Dwemer steamwork technology? No one, in 1000 years of magical and technological research, can figure out how to make a simple gun? A hand canon, even? That is some fairly weak line of thinking, there.
