Just a thought more than anything. In a lot of RPGs I have played that have carry limits it only applies to the player, yet any sort of container has unlimited space.
For instance the boot/trunk of the car in fallout 2, or the chests in Skyrim and the Bethesda fallout games. Especially with newer games offering crafting systems it seems the inventory limits are at odds with players being creative. In all of Bethesda's recent titles you collect mountains of materials that at the time have ambiguous application. Then later on you find out the snake toothbrush bristles you found make the best ammo in the game but you sold or dropped them to free up space.
I suppose my point really is: should RPGs think harder about how they manage your inventory as far as items that aren't immediately essential go? Or do other players enjoy the risk/reward factor of lugging about tons of items they can't really say are useful or not?
As a side note MMOs don't really seem to have the same stipulations, although I suppose most if not all the items aren't as rare.
