I wonder if there's a more flexible system for deciding how much you can carry as every system right now seems to be very black and white. You can either carry something or you can't and, as in Oblivion, if you carry 1 gram more than you should you immediately can't move.
A system that lets you carry anything (within reason) up to a limit and then beyond that your speed and stamina slowly decrease. Much more realistic and much less frustrating for the player.
It's that problem of realism v fun again.
I find encumberance and limits on what you can carry really frustrating.
I find that if i have to make a choice and drop some gear, i never go back for it.
Which is really frustrating.
Other systems have been used in games to circumvent this.
Teleports back to town and then back to the loot, or loading up a pack mule or another party member and sending them back to town with the gear.
Or a magical endless backpack, where any amount of objects can be placed in it with no weight restrictions.
Just get rid of the encumberance system in the first place.
As it's just a barrier to fun imo.
A hangover from the old D&D system.
