I’ve been a player for a few years and a dm for a few months now.
Hearing this as a player would completely kill my immersion and turn the campaign into an arcade game in my head. If you are allowed to say this, then I am allowed to hot reload when doing something stupid because having my pc die would throw out all of the work I’ve put into them and their back story.
Otherwise everything feels like a waste of time; like I’m misssing out on something else, something better, while doing it.
This makes me think that the real issue isn’t that your attention span is small and you get bored or can’t pay attention, but that you can’t “slow down” and enjoy what you are doing that moment and instead you keep thinking “I could be doing this, or that”.
Seems to me like these are two different problems (mind you I’m not an expert or anything, just sharing an observation I made)
