I don't know if thats on all platforms or just PC, I also don't know how reputable the site is so don't try to get me there I warned you in advance.
Based on the fact Mojang rebranded Minecraft as "Minecraft: Java Edition" and made the Bedrock Edition the 'proper' "Minecraft", I'd reckon the 75mil is across all platforms.
Also they're a fairly trustworthy site
I think VillageCraft can(should) offer something that can't be done in single player (The economy we have now doesn't really count in my eyes it is too bare bones). An more in depth and active economy is something we can do to set the server apart from the solo experience.
In responce to this, I've been doing a lot of random coding in my free time, slowly building up a library I hope to properly add more things to VC. My course is very busy, especially these past few months (which is why I haven't been on as much), but in some of my free time I've been trying to push Spigot/Minecraft to its realistic limits, to see what can be done with it. That, combined with some of the changes coming in 1.13, should allow me to add some pretty cool things to VC. I've got some ideas in the back of my mind, but I don't want to announce them until I can make sure it's feasible to add.
Oh, and there's something else I've been working on for literally ages (the oldest file is nearly 4 years old), which will help set VC apart. It's a huge project though, so no promises as to when that'll be finished.
