Character creation/editor would be amazing.

A quest log would be great.

A status screen.

Skill increases/level up.

Unlimited time

Choose your own appearance.

Volume adjusters

Balanced economies.

Health Potions

Infinite wealth exploits that the average person can exploit without getting into trouble. I could especially use this feature.

Though, a more serious answer would probably be something like infinite resources you find in certain games. For example, infinite weapons in games like Fallout 3, NV, and 4 from enemies periodically respawning when you're gone. Or in sandbox games like minecraft, how you can easily get seemingly infinite trees and bonemeal without completely destroying the ecosystem.

Fast travel.

A pause button

Mushrooms that make me grow tall and gives an extra life. Bonus would be the fire flower.

Stacking items and having it only take up one inventory slot in our backpack!

Quest markers, always providing information on how to progress

Detailed options so I mute background chatter or silence selected NPCs.

Subtitles for conversations not in my native language.

Being able to choose between single player, coop, and multiplayer.

Respawn.

Carry as much as you can fit into your inventory and ignore the weight.

I play a lot of VR and I catch myself trying to use the gravity glove to pick things off the ground

Difficulty setting. I play on easy mode and DGAF what anyone thinks because my time is precious and I’m playing for fun. I decide what’s fun.

Creative/cheat mode…let me just pause, build myself a fantastic 10 story house… Open inventory and spawn a wife, 3 kids, a dog and 2 billion dollars in my pocket. Oh no, does that mean I can't get achievements because I cheated? Oh well.

Steal a car, lose the cops and it’s mine now. No consequences.

Important story moments of your life play as cutscenes which you have no control over…so you can’t mess it up and know you’re exactly where you should be. This would be peaceful.

Hints & tutorials.

Play as a different character.

Choose your appearance instantly -gender, body shape, skin/eye/hair color, size of nose/ears/eyebrows, clothes, accessories

Things you buy spawn instantly wherever you are

Change tattoos instantly, including removing

Closed captioning for all dialogue and other sounds

Increase skills simply by grinding, even for things like skateboarding, singing, playing music, acrobatics etc that require raw talent and YEARS of training/practice

Inventory packs that seem bigger on the inside.

Like seriously, how does Red from Pokémon carry a whole dang bike in his backpack? Imagine trying to smuggle that across toll booths.

Bug reports

God mode and no clip mode

Pause screen

Free repec my self. Want to take all the work I put into my current career and relocate it somewhere else.

Infrastructure designed for a fun game experience, not cars.

Running and jumping all the time without issue. I'm not old per se, but I'm no spring chicken. I'm only 35, in decent shape, and I have a pretty active job, but I still cringe at the thought of the sheer impact of landing from jumping as high as I can. I was not kind to my knees in my late teens and early twenties. And I'm so goddamn tired.

Gameplay balance.

Inventory autosort

character creator, shove a RobCo Reflectron in the newborns face so they can generate their preferred potato look

Emotional reward.
