1. Why is the interaction with food bad for 77?
It's bad if it doesn't add anything besides a lame animation to show said interactions.
2. why is the interaction with chairs bad for 77?
Same as above.
3. Why is a sleep or wait mechanic bad for 77?
Same as above.
The questions we need to ask are these: what are you doing, eating/sitting/sleeping etc. around, what do you get out of it? How does doing these things help you play the game, or empower you in the game world.
I get people want these things in order to "become" the character, feel more immersed while playing the game. But here's something you should notice: activities which increase character immersion are not superficial or unrelated to the overall gameplay.
If such mechanics are added to the game, then they need to be more than just animations, meaning that they would have to be mandatory in order to be credible and believable.
You can't halfass this shit- if you want realism, then you'll get fucking realism: you need to eat every 6 hours, or else you're hypoglycemic and die, you need to relieve yourself and shit, or else you wet/brown your pants, you need to sleep, or else you hallucinate/die.
I don't understand the point of adding realism if it's not real. It's just vanity, it's just a gimmick, so why have it? Just so someone can pretend to pee after having a drink? What's the point of that for the game?
This isn't just a role-playing game for the sake of role-playing, it's a game with its own story and objectives, and everything in the game world needs to make sense within those two things, otherwise it's just bupkis.
I would rather the developers add inherently unique interactions to the world of CP77, somethings which our characters can only do in this game world. I would like options for interactions with the game world to be meaningful for character empowerment.
More importantly, I think it would be cool if they added things that we would want to do again and again because they're fun. I mean, how many times are you going to eat/sleep/piss/shit before the novelty wears off? What then?
I don't think CP77 is the game to innovate these mechanics into something interesting, it has its own objectives, and I think that's cool.
