One idea would be:
No Man's Sky, but made by a much large team, and as a Dwarf fortress like game, with a hint of Rimworld, Stellaris, EVE Online, and other such games in the mix:
- You would choose between a couple races at game start, with various advantages and disadvantages compared to each other, races which exist throughout the game and colonize the universe. There are also unique races, but those only exist at one place in the universe, and cannot be chosen by the player at character creation. Such unique races might be xenophobic, and attack anyone not of their race on detection. And they may have unique technology not available any other way.
- You would also choose an education (class), which gives you advantage in certain areas of skill. For example you could be a pilot, so you can fly a single person space ship by your own. Or you can be a mechanic, able to build and repair space ships. Or you can be a miner, and know off the bat how to create and run mines. Or you could be a medic, skilled at healing people. Etc.
- By default you would start as a young person without resources, just fresh out of school, not even owning a space suit, a weapon, or anything else. You either would have to make money somehow and buy a starship, or build one on your own.
- By default you would start in a giant galaxy (10^14 star systems) and would want to travel inwards. The starter galaxy is peaceful and is controlled by a single, benevolent and tolerant faction.
- Star systems will be modeled realistically. Planets will have realistic sizes, a realistic distributing of types, realistic moons, etc. Aside from star systems, galaxies will also feature objects such as brown dwarves, and wandering planets. Black holes will exist and will, unlike in NMS, be portrayed realistically, i.e. at the center of a star system. But, just like in NMS, they are a means to travel especially large distances at once.
- The game for a long time focuses on getting equipment and improving it, such as space ships, hand guns, space suits etc, including getting artificial or genetic enhancements for your player character. Artificial enhancements will require energy and maintenance. You will also later start building bases for yourself.
- There will be plenty variance of all these kinds. For example, there will be city space ships, which are huge and wont be realistically available to the player until much later. Or bases may be space bases, which dont mine resources, but may for example focus on doing science, such as observing the universe, or may grow food, or may build and repair space ships, etc. Or bases mining asteroid fields. Etc.
- Once you managed to reach the core of the galaxy, you can jump to other galaxies. The larger the galaxy you're in, the further you can jump. Only at the core of giant galaxies you are able to jump to other giant galaxies, which are extremely rare and extremely far away from each other.
- There would be a huge variance in galaxies. For example there are some very rare giant ones with about 10^14 star systems, a small number of large ones like our Milky Way with about 10^11 star systems, and the majority being dwarf galaxies with ca 10^8 star systems. There will also be all kinds of Galaxy types. For example dead. Dead galaxies have near zero free gas, dont form new stars, and only have old red dwarf stars. There will be no life and no factions, but you can harvest minerals etc relatively uninterrupted, except for other miners, and pirates.
- There would also be a huge variance in planets. Most planets will be without life. Many will be gas giants, and you will only be able to farm gas from them, but not land. Others will be city planets - completely covered in buildings. And some will be with life, but unconquered, though those wont exist in the starter galaxy. If there is life, it will usually only be primitive. If there is complex life, there isnt necessarily also sentient life.
- Once you have enought resources, you can start hiring no player characters, first for your spaceships, then for your bases. NPCs can be of player races, or they can be robots. Rarely you may find NPCs for hire of unique races, with an unique set of advantages and disadvantages.
- Permadeath. If a character dies, they are dead. You can keep playing with other characters you have, unless everyone died. Since you can control multiple space ships and bases and each have their crew, after a while it shouldnt be a problem anymore.
- Over time your character gets older and in the end dies. You can find a mate of your species and procreate so your kids can take over.
- You can build bases in occupied space if you can find an agreement with the ruling faction (that typically requires paying taxes), or you can find planets outside of occupied space and build bases there. You can also try to build bases in occupied space and fight off the faction thats present there, though that probably wont work unless this faction is weak, unattentive, too occupied for example with a war, or likewise. Bases allow you to mine resources close by, and do many other things.
- You may either form an own faction, or join an existing one and progress in it. Once you control a faction, you can do all kinds of new things, like build superstructures, terraform planets, declare war on another faction and possibly conquer space from it or force it to merge with your own, etc. You can also choose different kinds of rulership for your faction, like democratic or dictatorial.
- At any point of the game you can pick a character that is within the group of characters you control, and control them directly. Up to the point that you can even leave your current employer with this character and start a new adventure from scratch again. The computer then models within reason what your old faction would do. This way you can for example play a race not usually available to players. This is within the game though, for example if your faction is dictatorial and your newly picked character is effectively a slave, they will have a very hard time leaving (they would have to manage stealing a space ship).
- The game will always be 3D. First and third person will always be available. You have to point your guns successfully to hit someone.
vv221: Everything is perfect in this game:
dtgreene: I find this highly doubtful. In fact, I'd argue that there's no such thing as a "perfect" game; there's always something that can be improved.
(Note that this is true regardless of the game being discussed.)
Counterexample: Chess.
Thus, you're wrong ! ;-)
