Anybody know the total number of items in this massive game? Weapons, armor, ingredients, random stuff, etc?

Any reason why you need to know?

An exact number, damn. Too many to count. I don't think even uesp has an answer.

Since items are spawned in containers, the actual number is infinite as long as you play the game.

If you want to count the number of items that are placed in the gameworld and not in a container, you can load up the creation kit and figure that out. If the Export function is still there, it would not be that hard to put the list in Excel and count them, especially if the game tells you how many times something gets used.

I'm on Xbox, so I can't check the CK. Any idea how many unique items there are?
