Not to mention, it may be difficult to sell people on something that appears to be mostly cobbled-together free content. While it’s not illegal to re-sell Minetest and mods folks made for it (it’s all open-source, so commercial use is valid), anyone who recognizes the content isn’t going to buy it unless you make it really clear what value you’re adding.
Either way some heads-up would’ve been appreciated, since it looks like something I made is in there (I hope you kept the licensing in those package by the way, I haven’t checked but if not you may have some copyright violations). I imagine if you’ve actually taken the time to make a polished product using your own work and the components you found, then some folks in the community around the Minetest platform would be willing to help spread the word.
