Yea but as time goes by technology progresses. Not everyone uses magic, and guns make a lot of sense as time goes by for several hundred years. People are not going to use bows and swords forever.
You're just thinking in real-world terms too much. It does not have to progress in that same way. As a matter of fact, I can guarantee that it will
not progress in that way and it will take an entirely different route, because that's what the Elder Scrolls series is known for.
I also see no reason at all whatsoever why people can't use bows and swords forever. They've been using them since the Dawn Era.
Exactly. But you don't make those rules, and just because it runs on different rules doesn't mean that guns cannot exist. They may be invented in a different way entirely, but they can still be there. Or they may be invented in the same way and still be there. The point is that we don't know. It's a fantasy universe, and anything can happen.
Just because you don't like the idea of guns doesn't mean that they're not feasible in the TES universe. Besides, if Bethesda was able to retcon stuff for Oblivion, they can do it for Skyrim, too.
But the moment the game becomes a first-person shooter, that's the moment that the genre changes. By implementing guns that are able to shoot people in the traditional manner, it's not the same type of RPG anymore.
