This seems to be the effect in Minecraft, too. The initial draw to Minecraft was that it was a ridiculously simplistic sandbox, but now users want an infinite number of improvements: better textures, anti-aliasing, better shading, and less "blockiness".

It's an effect in pretty much any piece of software. See also Firefox, which used to be prized for it's minimalism, but is now considered bloated next to Chrome. Eventually Chrome will get Minecrafted too.
