I think, at this point, most of the nostalgia is for Skyrim, despite being the newest one in the series, it is nearly 14 years old now and way more people have played it. It had issues, and lost a lot of what was great in Morrowind, but it’s a beacon of quality compared to what came after.
It’s started to impact their success though, starfield has only sold like 3 million compiles so far, compared to the 12.5 million of fallout 4 on launch day. Hell, Morrowind has sold 4 million copies, albeit over 23 years.
It’s probably to late for Bethesda to turn things around, but, it’s a great example of what not to do for other studios and publishers.
