Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

PollyMC is a Prism Launcher fork but with "offline mode" and works perfectly on my opinion. I recommend downloading the flatpak version as the appimage asks you for certain versions of Java that are easy to install but sometimes gets a little complicated.

And yes, Micro$hit can eat shit. I personally bought Minecraft but on the day I was forced to migrate my Mojang account to a Micro$oft account with the threat that "If I don't do it I'll lose access to my game" I delete my Mojang account and use PollyMC since.

The best solution would be to install Prism Launcher from Flathub. This method is better than relying on downstream projects like PollyMC which may have delayed updates and be abandoned anytime: To avoid having to sign in to Microsoft spyware to play, do the following, credits to this guide:

First, open Prism Launcher, then close it. This is to ensure that the account data has been initialized.

Second, run this command on the terminal:

echo '{"accounts": [{"entitlement": {"canPlayMinecraft": true,"ownsMinecraft": true},"type": "Offline"}],"formatVersion": 3}' > ~/.var/app/org.prismlauncher.PrismLauncher/data/PrismLauncher/accounts.json

Third, open Prism Launcher, press the account button on the top right, create an offline account, and set it as the default account by pressing the Set as Default button on the right side of the list. After this, delete the No Profile account by pressing its entry on the list and selecting Delete on the right side of the list.

Done! You can now play Minecraft without the Microsoft account BS.

~~Note that I do not support piracy, but I cannot tell you to buy Minecraft first before doing this because I don't want to be a hypocrite.~~ lmao i didn't notice what community i'm on lol

I use UltimMC (MultiMC with cracked support).

I know this isn't the question you asked, but have you tried playing Minetest game?
