Arrrr my fellow pirates. Since I'm very unexperienced with the seas I ask for you guys, where can I get Minecraft from for Arch Linux. It's not because I'm not willing to pay 20€ but because Microsoft is a giant bitch and I'm not willing to put money in their mouth(especially after they changed their privacy policy).
