The other pc versions are "free" so you have to buy lava stones and other items, I bought my game on a half price sale day so I consider it a good value even with a couple minor glitches that don't effect the overall game play to much, I think in the long run it is better to buy the game than to pour money into a freebie. If there are any new VV games coming in the future I hope they are made for the pc player to buy like the great older VV games, it seems the devs and game sites are catering to the facebook crowd who only play free games on mobile devices and us pc players who prefer to buy a good quality game are getting the short end of the stick. I don't like this trend in gaming, I don't have a facebook account and never will.
