Originally Miencraft, then terraria, Starbound and finally Shovel Knight.

Starbound still has to deliver more though.

Man, nothing fits the answer better than Minecraft. That thing exploded into one of the biggest games ever... o:

It's a surprisingly bad game for having so many sales.  Outside of creating anything you want, it's got some of the most boring mediocre gameplay.  I can't comprehend why so many people love the game. 

It's literally one of those mind blown things that something so bad can make so much money.  Then again, there are three Sharknado movies.
