I forgot to mention:

If you've got a horse or a cart or packmule, what you can carry goes up by a LOT. Now, in actual war scenarios, medieval knights and well-equipped footsoldiers would have squires and carts to hold things like lances, halberds, and etc.

An adventurer doesn't always have those luxuries, but if you do, don't forget to consider that.

And one big note: BACK. SHEATHES. DON'T. WORK. You can't really keep a sword sheathed on your back. Don't try it. It's bad for you. And on that note, you can't sheathe claymores! Or anything that would probably qualify as a 'greatsword!' You might have a scabbard for them, but you certainly aren't going to be able to wear it while walking around in your daily life. You'll hit every door you try to get through and it'll drag on the ground and etc. Not good. Just carry the greatsword in your hands.
