This is a little unusual. Most games never explicitly say you need an SSD or a HDD - but Starfield does! This likely isn’t a hard limit, as recommendations are often just that, but I cannot help but wonder what would happen if the game is run on an HDD?
The loading times will probably be very long.
Loading pains seemed likely. Bethesda games have traditionally been on the longer loading side of things
I can remember keeping a book at my desk because my computer could barely run Morrowind and the load screens took forever.
The loading times for PS3 Skyrim used to be something else, was spending more time in loading screens than playing the game.
