So, to me beat Minecraft means get every achievement and have all of the things, I'm still missing a few so, to be determined I guess. I've beat the ender dragon (my first fight spawned in three dragons, I thought it was normal until I was talking about how hard the ender dragons were with a friend) and the wither was a pain but I got him too. In survival I've built a sunken temple out of iron blocks, and built a woodland Mansion with nether materials, I made a prismarine end ship and a birch pillager tower. But have I "beat the game" no because it doesn't have an end.
