ED is not a sim: Here is its marketing description:
Elite Dangerous is the definitive massively multiplayer space epic, bringing gaming’s original open world adventure to the modern generation with a connected galaxy, evolving narrative and the entirety of the Milky Way re-created at its full galactic proportions.
Starting with only a small starship and a few credits, players do whatever it takes to earn the skill, knowledge, wealth and power to survive in a futuristic cutthroat galaxy and to stand among the ranks of the iconic Elite. In an age of galactic superpowers and interstellar war, every player’s story influences the unique connected gaming experience and handcrafted evolving narrative. Governments fall, battles are lost and won, and humanity’s frontier is reshaped, all by players’ actions.
No mention of sim anywhere...
It is a semi-arcade sci-fi game with no claim to reality outside of the size of the game world (Mily Way sized)
Semantics, and marketing materials are usually weird, for everything
The Game simulates environment very well (Stellar Forge is the best), but it is "space sim" in the game meaning. How to show realistic future?
The same wih MMO... I know... it is called MMO, but it isn't usual MMO...
I preffer to play the game than words in this case tbh
