Does Stronghold have to be in 2D?

Contrary to probably most of you, my first Stronghold title was Stronghold 2. So when I think about Stronghold I think about 3D graphics.

But I have realized that especially when Firefly announced new Stronghold titles in the past, many players, it seemed, were hoping it wouldn't be in 3D. Ofc there were many disappointments especially with 3D Stronghold games but that doesn't automatically mean that 3D is bad, right? I mean Stronghold 2 should be a good example that shows it can work.

Apart from the disappointing 3D titles in the past I cannot really understand why Stronghold and 3D shouldn't fit together, so why is the community so certain when it comes to that?

Edit: Generally speaking: So why does Stronghold 1 deserve a rework (which ofc it does) but Stronghold 2 doesn't?
