Runescape has a similar thing going on. What everyone's not understanding is not that improvements are bad, lots of the player base also want to see games evolve. It's just that a significant proportion of the audience also like The Old Thing and they're often more engaged as an audience in the first place.

You hear this story over and over about every kind of software.

There are two audiences every successful developer needs to cater to: the "I wish this did X, I want new features" side and the "I liked it the way it was" crowd and they're distinctly different groups.

For a long time I produced a popular technical art asset for video games and even I realised I needed to include every single version of the tool with every single installation. If a developer has to go and find out how to get "the right version" at all then I'm 90% likely about to lose a user.

Focusing on the "we did this right just keep going like that" and really understanding WHAT you did right and WHAT people like is really important. It's really hard to be impartial when you made the world rather than consumed it, but always take the win.
