Minecraft stands out not only for the way it inspires me creatively, but also because of its unique aesthetic. Look, I know the visuals look dated and a bit silly, but few games have visuals so endearing and charming. I know I'm not the only one who feels that way either, or else Minecraft's graphics wouldn't be so iconic. Could you take a texture from Gears of War, Halo or Uncharted, put it on a shirt and have players identify it? I doubt it. The looks just work, giving the game a super unique appearance that's memorable, and brings up a bit of nostalgia in me for 8-bit era games.
I think minecraft will still have players in 2020.
