Being unable to open (kick in) a wooden door as a level whatnot Dragonborn because it is "locked". Looking at you Skyrim and Assassin's Creed.
Being unable to jump over a small hurdle or being allowed to climb only in certain situations like in Far Cry 6. Like, is this a Parcours game now or what? There's even a Parcours "armour" set.
Terrible inventory GUIs. AC Valhalla is one of the worst games inventory-wise. Decades ago video games did the job perfectly, there's no excuse for best practice degradation
The being unable to open wooden doors is also so weird in games where you HAVE lockpicking.
Like in skyrim you can be a master lockpicker with the skeleton key, yet some locks just... require a key? Flying in the face of all game lore.
Why do random houses have these magical locks? I understand it's for game design, but put important stuff behind things that reasonably block the player!
