It's not based purely on D&D, but another ruleset involving vampires. Look at Vampire: The Masqurade - Bloodlines. Sure, we should all remember it, and continue to take ideas from it, but expanding past it is critical. Staying true to the D&D heritage is becoming less and less reasonable, as we no longer need the D&D ruleset to define games. Because you need almost everything you can loot for your settlements, crafting, and just for some people the collection aspect. You're not planning your character out at the start and trying to min/max bringing a light, fragile weapon along with extra potions or a heavy weapon in the place of them, you're basically spamming the loot, loot, loot button as fast as you can. Yet in a 3D game where you can literally loot EVERYTHING, it seems kind of pointless to enforce such a restriction.

This was translated into 3D games as sort of a translation of the system. You can have a bag of holding, but that takes a movement action to utilize, depending on the rules, but expands your carry weight. In D&D, what equipment your character starts with, and keeps, is completely dependant on how much you can carry. Video game carry weight is something that RPGs had a long time ago as a translation of Dungeon & Dragon's carrying capacity system.

Not having carry weight or making it toggable for 'realism.'.

Automatic storage of all workshop materials in a workshop.

Weight limit that increases as you progress through the game, providing a limit to the amount you could loot at the start of the game, and progressively bringing it to an almost unlimited capacity later on.

Weight limit is for what you can physically wear, restricting better armor and gear to higher strength characters.Actually, there is probably a bazillion other ways to handle carry weight, and using Fallout 4 as an example, here are some off the top of my head: I think carry weight should be an opt-in thing, especially as games add more and more things to jam your inventory full of. Let's get something straight - the fact that most players I know use cheats to get past the carry weight limit in Fallout 4, Fallout 3, Skyrim, and many other games (Witcher included), is just showing how dated the idea of carry weight is.

The command 'tgm' for God Mode also makes you immune to encumbrance from having too much in your inventory. Before we get started, in order to get past the carry weight limit in the game, you can open the console (~) on PC (sorry console, there is no helping you), and do the following:
