Will there ever be a simple, but successful PC game similar in success to Minecraft soon?

Not a game with Minecraft's style, blocks, monsters, mining, crafting, etc., but a game that will have success like Minecraft on PC, just a simple game that mostly anybody can run on their PC?

Modern Warfare and Black Ops series on Steam. That is very popular if that is what you mean.

I'm sure there will be something soon since people are playing indie games more and more.
