So we have:

Dagger
Sword
War Axe
Mace
Shield
Greatsword
Battleaxe
Warhammer
Staff
Bows

What about flails? or spears? or crossbows or nunchucks or knuckledusters? Wands? Halberds? Claws? Club? Longbow?

Why werent they put in game? "Because they didnt have time"? "Because the mechanics are too hard to put in"? "Because they wanted to balance the game"?

We've seen that spears can work, they could have made it a rare item that only shows up once in the game, so then it would be balanced.

Though I love this game, swinging around with an axe and shield starts to get boring. Im not interested in being a mage or assassin, Ive already gone through every quest. Maybe ill stop playing for a year and forget the storyline, but for now im sticking with my main.

Well, as Todd said, “we can do anything, we just can’t do EVERYTHING”. I believe they ultimately had to make a design decision at some point that they would include this set of weapons and stick to that just to move forward. Hopefully the spear lovers will get their wish in some new content in the future. Otherwise you’ll have to resort to mods if you’re on PC.

On the other point of truly unique weapons, I was saddened to find so few truly unique weapons in Skyrim. Most are just enchanted vanilla weapons, not truly unique like Dawnbreaker.

there's no unique weapon type, but there are some unique weapons like Dawnbreaker
