Some people, yeah. But a lot of people only enjoy the game because of complex systems that were added later: redstone, slimeblock machines, building complex farms, gear progression via material and enchantment upgrades, exploring an infinite world, etc. You can go on Youtube and see people who only play those parts of the game. I think it's fair to say that they wouldn't have enjoyed, say, Indev, before those features were added. And Indev, before the infinite world, was already the culmination of 6 months of work on the game! That's pushing the definition of "small game" already, and a lot of people would still treat it as "a cool toy, but not a full game" (I played it back then and remember people talking about it as such).
