Minecolonies is not the same as Simburbia, they are different kinds of experiences. And the conversion of Simcity saves is not the same as having a functional SimCity clone in Minecraft. And I am not saying everything on Bedrock is good, or that Java is bad, they’re just different. You might not like the crossover DLC, but they’re fun content you don’t really have on Java. You don’t have to go and play Bedrock if you don’t want to, I am just giving a reason why someone might want to.

there’s some incredible mods and maps for Java but there’s also a lot of fun content on the marketplace. The Sonic, and Ben 10 DLCs comes to mind, there isn’t anything like that on Java. It’s a difference of someyhing like Minecolonies, a detailed automation mechanic integrated into the survival game vs something like Simburbia, 1:1 recreation of SimCity that exists entirely separate from the survival game. They offer very different kinds of content.

While the marketplace on Bedrock is filled with garbage, it’s does also have some genuinely fun and interesting content that’s not really replicated on Java in my experience.

You’re thinking of PolyMC, where one of the devs went on a powertrip and kicked all other devs out. The devs of that then went to make Prism. PolyMC splitting off from MultiMC was a whole other mess.
