Ya , bro , just look what they are adding with every new versions and how they present it. It's fire! And they also polishing it and making it bigger and bigger so I think it won't lost it's popularity that easy. It's like Lego. Even after 90+ years they still dominate and no one can compete with them. They just choose working unique idea and and made it so good that no one can imagine something better, so Minecraft is the same thing. it's just simple blocks. You add 1 block to another and you have simple house . So ,ya. They already dominating like 95% of market with similar games and I don't think someone can imagine something better and make it real banger , like Minecraft did
