I believe everybody has heard of Minecraft. It is a deceptively simple game, that was made by a single indie developer, and sold more than 500k copies - despite having no active marketing and being technically a buggy alpha-version.
That is really great success for an indie game. And I think we can all learn much from it. So I want to examine Minecraft's game design: what, in your opinion, makes it so great? What choices work well, how they combine together to make a great game? And what design decision are bad (I don't think everything is ideal in Minecraft)
What do you think?
