Are there prebuilt maps to use for the editor? Or tilesets imitating a map that I can use?

I don't know why you would want pre-made maps if you're trying to create your own game? I would suggest looking at tutorials for RPG Maker mapping if you're having trouble getting started.

I'd have to agree with @WereAlpaca

I find the best way of learning map making and the tools is just to start with good ol' trial and error.

I'm sure you could also pay someone to make a map, but might not be a great use of your budget.

I imagine he asks for a team work type of thing, or the option to collaborate with multiple people world building in 1 project or just sharing cool dungeons n stuff?

I'v known a few people who like to make worlds and wallpapers n stuff like that, in other games they call it seeding i think.
