I think he meant the application GNOME Software. Only valid point, I would like to be able to install or at least update my arch packages through GNOME Software like I do with flatpaks. Doesn’t have anything to do with the way Arch works tho, it’s just that no one has made a plugin yet that allows this.
You can’t really torrent it, the game version gets downloaded when you start it, so you’d either have to torrent every version you want to download or download everything at once, which would take way too much space. The thing is, you don’t even need to. You can make an account without buying the game and you can still play it. There’s dedicated launchers for playing the game with an account that doesn’t own it.
Also, Veloren is not similar to Minecraft at all, even if it’s still a very good game. There’s Minetest tho, which is also open source and it has a gamemode as a mod, which tries to be a copy of Minecraft.
