In TTRPGs encumbrance seems to be the #1 rule that players conveniently forget about and GMs only ever seem to bring up when they want to fuck with the players. It’s probably one of the more annoying, unexciting aspects of TTRPGs to keep track of. I like the approach that BG3 has taken, you essentially have an unlimited Camp inventory, but your personal inventory is limited. Is it realistic? No, absolutely not, but neither are Bags of Holding, which are basically a GM’s way of throwing up their hands to say, “Fuck it, I’m not dealing with this shit anymore.”
