It hardly can be named any other sphere where the process of development is as fast as in the gaming industry. New technologies constantly emerge and it became hard to define the source of innovations. Still, there are some games which present a kind of mile stones in the history of gaming.
Some of the most innovative games are almost forgotten nowadays, but still the technological level provided by them remains in great demand. For instance, I doubt that there are a lot of fans of “The Flower game” issued in 2009. In this game you will find no enemies, or bloody wars, or complicated missions. You just guide the petal through its way and make it produce sweet sounds when touching the other flowers. The novelty of this game is that no words are used to create the plot – there is just you, music, and flower.
