World of Goo was a very innovative game at the time. A puzzle game using physics in very unique game design. The music, combined with de strange story and thoses tinies "goo", made it very interesting. A lot of replayability. Diferent ways to complete a level, it was one of the first game to promote the "build your own solution" on level designs. The game itself deserves five stars. But I also give five stars for being one of the first indie game to really be absolutely "DRM free". At the time, there were no strong digital plateform to sell the game. You've got to go on the WoG site to buy it, and get, not a installer, but a notepad document instead, with the URL in it with where download the setup files. The URL was unique, without any protection. The developpers made the courageous choice to have an absolute confidence in the customer's ethics. For being so trustful in those times, WoG also deserves five stars.
