I think Minecraft: Story Mode is getting a second season because Telltale is trying to expand to wider audiences, something they can’t do very well with TOTBL or TWAU. Not that those aren’t good games; they’re great games, and deserve more attention. I really do hope that they can get new seasons too.
Not to mention that mcsm really isn’t the horrible cringefest that everyone makes it out to be with all the “mInEcRaFt CrInGe” bullshit. Yes, it needs improving, but having played it myself, it’s actually a really fun and enjoyable experience that me and my sis had far too much fun with. I feel like a lot more people would like it so as long as they gave it a chance.
