I bought Game Dev Tycoon, almost entirely to spite the people here who were saying the false-torrent controversy would hurt the company (it did literally anything but). The game was pretty damn good, too!
Also, I saw a bunch of people somewhere else having a full on verbal fistfight over whether or not "Yume Nikki" and ".flow" were even games, let alone whether or not they were good. So I played them... they were very good, indeed. They were just very different (literally a genre of their own) and rely heavily on fan theories.
