Traditionally, the Minecraft Now livestreams are just an opportunity for players to interact with members of the Mojang team, asking questions and watching them play and build in the game, while Minecraft Live is focused on new announcements.
While both livestreams are great fun to watch if you’re a big fan of Minecraft, if you’re only looking for details on coming updates for the game, you’ll only want to tune in to the Minecraft Live events.
