Ian M Bank's "Culture" simular to the foundation series
(where robots and computers effectively are so capable they manage everything, but choose to create utopia for people because it actually is the most interesting an ambitious project)
Robots / machines that clean / perform maintenance / servicing / replacements etc
Nanobots injected in you that see to your health, create whatever drug effect you wish, change your body to whatever you want it to be (want to be an octopus ? => fine)
Argumented reality is good - my eyes have map overlays,
"Complementory peronality/mood" detectors, ie your feeling like venting about topic X => that sort of conversion Y is probably in the mood to share - that person is highlighted on your bionic eyes.
"Thought-deducing Attitude / interest directed training machines", it knows what interests you and doesn't bore you with what doesn't.
End of money (star trek like concept of trade), no social class differences.
"Idiocy / mundane logic filter for voting" for news and voting => Anyone that has a stupid opinion doesn't deserve a vote nor air time.
"Bitch/Bastard viruses" => Viruses that kill off those systematically enjoying bitching or being a bastard for instant social kicks / to make themselves powerful unjustifyable at others long term expense
(released as a form of population control).
transport system that does its own thing - we get into a transporter or a pod and it takes us there without manually doing anything => Always smooth nice for the environment, none have private cars its all state owned - so no better than the jones issues (effectively taxi's that run themselves)
On the topic of games
a) Anything you buy from shops / can buy is displayed in a "what it looks like" window. So you you know what your character would look like with it BEFORE buying it, same with skills and magic, before you choose it you can see what it would feel like to have it.
b) Mood states for characters, when fighting instead of choosing every thing at every second you put it in a mood state "agressive / defensive/ evasive / protective" and it does its own thing, and you can flip between mood states and also out of fighting choose what sort of thigns your character will do under different conditions when in these states.
c) Horses in games (they are about you can ride them and fight from them
d) Ships done well in games
e) Things that are a required "level" to use => Thing of the past. If you have a super-dooper sword or super-robe, you can wear it ! The idea of "balancing for levels" doesnt make sense. If you are say effectively a level 1 and you have stuff that a level 100 has => thats ok.
f) Being zoomed out more, the smaller your character the more of the scenery you can have, the easier options you have for long range spells and ranged stuff, also the more buddies you can have with you without clogging up anything.
g) Seasons in games. Its winter, its summer, its raining, its dawn, its dusk etc, fog !! Huricane ! flooded !
h) Magic being less comical and more indirect, a sword that glows but doesnt really harm anything is silly. Swing it and you get all these strange effects that just look comical (doesnt feel real)
A lightning bolt that you shoot from your fingers should KILL things - not do them a LITTLE bit of damage.
When fighting you actually look like your fighting and your opponent is actually evading your swings, blocking them not just taking the hit and their health bar goes down
If your injured your injured and your actions change, you limp not just go around with a health bar that is lower.
