The thing is, though, it IS a valid point. Fantasy is not a game genre, it is a setting genre. If you have a game that's almost the same as Oblivion but takes place in the future with lasers and space battles, it's sci-fi. You can complain about fantasy never changing, but it's not really supposed to. How often do other genres "change?" The popular cliche of Tolkien-esque medieval settings are not the definition of fantasy, so that can change, but the more specific definition is a focus on magic and the supernatural. It's the specific evasion of scientific and technological themes that separates it from science fiction.
People keep disagreeing with guns on a "gut reaction" because it doesn't really have anything to do with whether they can theoretically make sense, and doesn't really warrant any argument. Guns are a risky addition just as magic is touchy to add into science or realistic fiction. People who want fantasy are going to disagree with guns, because guns move away from fantasy. That's it, pretty much, and it's always pointless to attempt to argue against preference.
A really BIG problem there is, TES, up till Oblivion was LOW FANTASY, there where actual "problems" in the world, politics played into the whole mix and i wasn't "good vs. evil" and "because the gods said so". With Oblivion they kicked it HARD into the "high fantasy" side which pretty much screwed up everything established so far.
I would be SO DAMN HAPPY if they moved further into low fantasy againa nd actually have a believable world once more. But no, move to high fantasy and cash in on all the LotR crazies, why be different if you can be marketable.
Morrowind was good because it actually dared to do things different.
The reaction to that wasn't pretty, as ya know it by now.
Yes they where but again, guns would not automatically mean the whole world suddenly tumbles over ina multiple summersualt.
One idea was that while they DO exist people don't use them much, they are very obscure and early ones are dangerous. But if you're small, weak and fragile and have to deal with a huge brute having something so strong and yet easy to use would be a good thing (one more reason why i'd put the guns in goblin hands, they're not afraid of them as they give them a advantage that can mean the death of one but the continuation of a whole "colony").
