There are 16 quests which are given to you by a daedric lord.
One is actually part of the Thieves Guild questline.
there are so many weapons on the game of skyrim with different effects and purposes but deadric weapons are the strongest of the lot even with bows the deadric arrows and bow are the best ranged combo on the game but they can only be made from scratch or if your lucky and are a high enough level you will stumble across them one one of your many inventions.
There are 15 quests in the stormcloak storyline, two of them give you an achievement, four are optional, one is missable and the rest are basic quests.
There are 6 main quests to do for the Companions, as well as occasional side quests (mini quests) you'll be asked to complete before getting to the next main quest. Due to how the game is set up, the number of quests you do might vary.
There are 6 'main' Companion quests, and 13 variant 'Radiant' quests, some of which are one-offs or otherwise limited. Some radiant quests must be done before you can continue with the main quests.
Because of how Skyrim was made, the missilanious quests are never ending. You can continue to kill vampires from talking to the Smith in Dawnguard just like talking to the night mother for another contract. they are unending. but great for gold.
