Minetest is free and open-source, right?
Well, I want to make a pay for game like Minecraft cause the Moderators for the forum for the MC game itself are being (in my opinion) Jerks.
So I want to make a game called Realm Of Blocks, but to make the trial version, could I modify the game after downloading, and present it to the Minetest forums for Approval, or do I need a license first? Is it copywrighted?
If approved, then I would put it on the Forums for Minecraft to see what they think of the game.
Then have a site for the game to be payed for and downloaded.
What is your opinion on this? If no, then I need a site that can has a reference guide on how to program in java that is free, and printable.
