Sorry for coming bit late for this topic. Kept reading it last 1,5 hours
Didn't you guys play New Vegas with hardcore mode? Bullets had weight, you were required to drink, eat and sleep. All that made the game much better in my opinion. Most frequent was the drinking and but even that wasn't too often.
That said I don't see CP2077 as similar survival game, so those options should only be added to the hardcore difficulty. Or like I'd want to see it custom difficulty with sliders and checkboxes to choose options. I'm totally ok with some hand move and eating or drinking sound, even that aint needed.
What I'd like to see more is situations like these included in missions/conversations/cutscenes. Meaning perhaps you corp and have mission having bussiness dinner. So you eat while having the conversation.
Or perhaps you're going clubbing and they show you getting out of the shower and dressing that best suit or what ever.
On a less serious note...pissing etc. Yeah and I want to be able to do it in first person. Maybe have a minigame where you have to pull out your junk, aim and take care of the drops.... And of course we would need different animations for male and female.
Also like Ironside suggested: I like the feature in games where camera moves around you when idle.
