Red- You get a UI that shows everything, including a combined inventory with unlimited carry weight and unlimited capacity and number. If the game does not have durability then the item is indestructible, if it does and it breaks. you can repair it with crafting stations.

You have an Equipped screen allowing to equip any combination of items instantly. Everything fits perfectly and is comfortable.

you can equip as much as you want at once, using real world capabilities to maximise it. such as putting rings on necklace chains or putting everything on one chain.

Effects of similar type across different things will stack. things like health regen and running speed and multi jumps. your HP number will be the combined value of all health.

Scores, Points, and in game currency all convert to useable real world money.

Consumables like Potions are restored back to whatever the original number was after 24 hours. (if you start with 4 and you drink 1 health potion, you will have 3 left. after 24 hours, it will go back to 4)

You can not hoard them, consumables do not resupply until they are used.

Consumables with similar temporarily timed effects will stack the effect and the timer, a potion of speed (+5% running speed) that lasts 3 minutes and a potion of swiftness (+2% running speed) that lasts 5 minutes, will combine to 8 minutes and +7% Speed.

Ammo is unlimited but you do have to reload or change ammo types if the weapon needs to reload.

Things that use up Energy with use and need ways to recharge will have a way to recharge them included with your Bases and Resources, including all work stations and crafting tables etc.

Blue - any NPC you have ever killed, civilian, merchant, monster, boss, companion etc. you can summon an unlimited number of that NPC, they will be Friendly and trust you but you can not control them directly, but you can ask them and lead them, They will not do anything they normally wouldn't, you can't ask a good character to do something evil, etc. If you abuse or mistreat them they will disappear and will no longer be Friendly. Your relationships can change with actions and time.
