I mean, sure, it's 5 to 7 years old depending on your count, and it has quite a lot of toys, but "lifetime" seems a bit of a stretch.

Star Wars has for sure stood the test of time, and I have no problem imagining Minecraft being Lego 2.0/Lego digital or something else entirely, but right now I see it merely as really great/pervasive product with some branding.
