I voted 'none' because I'm happy with the weapons present in Morrowind and Oblivion. The only things that I wouldn't loose sleep over if presented in Skyrim would be spears and brass knuckles.
As was mentioned, hand-to-hand was lacking in Oblivion, and definitely lacking in Morrowind. I think brass knuckles could add an interesting 'punch' to hand-to-hand-- more gore, bigger gashes, heavier damage. I would also like to see more martial arts influence in the hand-to-hand-- kung fu has some good moves for disarming opponents, and jujitsu has great moves for submissives. In Oblivion, I always wanted to use hand-to-hand against bandits, as in real life I'm quite interested in martial arts. However, having my forearms slashed by a sword, and immediately thereafter striking the opponent to death was unrealistic and turned me off to that option. If martial arts were present in Skyrim, as it should, I think brass knuckles would be unnecessary.
Spears would actually be pretty cool. I can't remember if they were in Morrowind, as I haven't played it for years because my obsession for it was killed by Oblivion. I thought I remembered throwing knives/stars in Morrowind. I could once again be wrong. I think these would be cool additions to V.
Guns: F**K no. Imho, crossbows are on the same page.
If guns make an appearance in this game, ill make an appearance in Todd Howards office....with a gun
:woot:
