Anyone who has ever played No Man's Sky has wished, even yearned, for some semblance of an actual living breathing RPG-like universe in the game.
When I saw the Starfield trailer, my first thought was, "HEY! This is going to be like No Man's Sky except... OMG, it's No Man's Sky sandbox RPG!!! I've been wanting this for years!! Bethesda gets it! I can't wait!!"
In video game development, a bit of plagiarism is a sincere form of flattery. It's evidence that No Man's Sky gets some things right, which it really does! The problems with No Man's Sky are rooted in the engine that makes the game possible: procedurally generated content evokes a feeling of randomness to that which begs for meaning. As humans, we are not accustomed to living completely separate from a society, which makes No Man's Sky's space stations, freighters, and trading hubs are very welcomed sight, but the planets are still about as meaningless as they ever were -- at least they were as of the last time I played.
When you play a Bethesda RPG, you know that everywhere you go, a designer has been there and had some thought about it and maybe even some intent. Not everything is elaborate, but when you come upon a glade in the woods you know to suspect that you're not the first to have stepped there and it's likely that there's just more there than meets the eye, which boosts the mystique of what you are seeing and hearing.
Games like No Man's Sky and Minecraft have always lacked this, which makes Starfield's borrowing of these concepts a whole new thing with the RPG elements.
