I’d like to see an end to the tired “invisible” inventory. If you have a quiver of arrows it’s slung across your back, if you have a bow, it’s there as well. If you’re carrying a sword it’s in it’s scabbard on your hip. A shield, also on your back or in your hand. Letters? Keys? Food? Drink? in pouches or in a backpack. I’d like everything to actually have a place, and that should determine how much you can carry. Maybe you’ll have a bow, quiver, shield and sword all at the same time. Maybe you also have a dagger on your other hip. A quick button selection menu could be used to determine which weapon you’re deciding to draw.
Maybe you use a halberd and a sword, so you’ve got the sword on your hip as you hold the halberd, leaning it against your shoulder (it would be silly to try and strap a halberd or spear to your back.) Depending on the situation you could throw down the halberd and draw your sword (maybe you’re in close quarters.)
Right I think you get the idea. Everything you bring should have a visible place in which it goes (and fits.) So if you wanted to have a second sword I suppose you’d have to sling the scabbard over your back (you can’t draw it, but for carrying only.) The more you bring the more it will fatigue you, possibly slow you down (because running with a bunch of stuff flailing around on your back is not the easiest thing to do, trust me.) It could also effect your stealth ability.
