Re: Guns...Will they kill it?
You have good taste. Funny books.
Yes, I got the comment-- that's why I responded to it, sort of.
You are, however, wrong. Speaking historically, for centuries bows fired faster than guns. Even into the 19th century, a bunch of guys with bows could beat a bunch of guys with guns so long as they avoided getting caught in the open and blasted at long range.
For a time, armor was also some use against bullets, and many creatures and characters in Fable would have natural immunities, to some degree at least. Trolls, Undead, Balverines (if they returned to the "silver only" thing for real), and possibly Sprites would all have some degree of immunity.
And I don't see how you mean "they always do the most damage they can". If you miss, or if the round hits something off which it can ricochet, and if you're far enough away even a book or a random lump of metal can block a bullet, especially a minie ball, the point at which the weapons look to be (to me) from the one demo shown.
However, they did (thank god) speed the reloading up for the game (again going from the demo), since what looks like it would have been more realistic would have been way too slow.
And, if you want to get right down to it, sometimes a bow can do more damage than a gun. If you get a bullet lodged in your skin, if it's not in a bad place, they can just sew you up and eventually it'll work its way out. With a arrow, the head has to be removed, because as long as it stays it will continue to cut you. That's just one instance of more damage. You can also set arrows on fire more easily and with less danger than you could heat a bullet or something.
I'm also not sure what, exactly, you're worried about. Except for the humans and perhaps the hobbes; and the animals/insects, everything is big, hulking, strong, and/or Will-infused-- why would they not have a defense against bullets?
