It’s crazy to me that WoW exists but I think there won’t be a WoW 2. But who knows i was wrong about this with StarCraft as well and StarCraft 2 has turned out OK
Anything they would add in a sequel is just added to the existing game.
Face it, AAA studios just can't do open world and can't do decades-long development cycles, they always immediately lose the plot beneath super-irrelevant graphics, platform deals/restrictions and other crap that's mostly openly detrimental to gameplay and ease of access.
That they insist on treating game development as movie production is my running hypothesis.
Rimworld also has non-inconsiderable female following, but only because it's a) very mod-friendly and b) in continued development for more than 10 years already. Its attention to relationships and interpersonal stuff also helps.
