mine aren't too serious (, kinda unrealistic) and probably will stay unnoticed but:
1) it would be kind of cool for the music inside vehicles to start at random points (radio is not supposed to wait for V to get inside of their car just to start a song) / mb its just a ps4 thing
2) flag created items as undismantable or make basic crafting components cheaper to sell (my hobo-v had already made a fortune just on selling magically multiplying scraps)
3)mb some dude to repair your car for actual money, I feel sad for those house elves that do it every time I call my ride
4) it's kind of noticeable that most of enemies can't leave their designated areas (I get the feeling, but mb they could come out for a bit and then return?)
5) most of gang members chilling around the block could take longer to get agitated, rn they're getting annoyed with V simply breathing
6)maybe add metro back? (obviously it won't serve any specific purpose at this point (except making the city more lively??) , but public transport is too cool to keep out)
or at least some running people
(it's almost like noone in nightcity works, ever, everyone just walks around their home or gets out for a chill ride, not including those few unfortunate souls that are forever stuck behind a foodstand)
7)leg cyberwear could be somewhat visible?? rn im double jumping just by sheer strength of my clapping asscheeks
8)more phone messages. mb some fun characters to send em (like those cameo peps, whom I found absolutely delightful!)). moogle-mail from psp ff dissidia kind of deal, but it's Jessy Cox talking about his new raging erection.
9)talking about raging erections, mb a couple of new partners? i get that Kerry is an absolute legend and i feel honored for being allowed to sleep with a recurring character, but he's almost a millennia old? it's like having an affair with your favorite AC/DC member, but he ignores his numerous children and just started his own makeup channel
10)paintjobs. for guns, for cars, for v's life.
11)a portable music player would be nice too and/or a vinal one for your apartment (you could even keep tracks as a collectible, considering they are already scattered around the city)
i won't talk about barbers, adequate shops or pachinko machines
cause everyone else had already mentioned them, but yes, they are desperately needed (v doesn't have literally anything he does in his spare time, mb streetbrawling and alcoholism
, but there isn't anything chill "to return to", like a baseball machine he goes to rewind to, or some homeless men playing checkers idk)
