I will be such a happy camper if we have spears and halberd again.
I honestly had a hard time getting into Oblivion because of the "Everything is a sword" style. Even the blunt weapons were swung around like a sword.
I don't really like magic much in any game, and TES are even more magic-shunned because of, imo, a not particularly compelling magic control system. But if a game has in-depth melee and ranged weapons, it more than makes up for it.
Speaking of ranged, if there aren't thrown weapons, I will be severely disappointed. What's more Nordic than throwing axes?!
RE: Fire swords:
I want a game to use uhh... whats it called... volumetric effects? The heat effects you see in games like Shogun 2 for fire. Anyway, I think the sword should just sort of Ooze that, like it's heated metal, then only actually flame when swung. That would be my #1 way to portray a fire weapon in my book.
