The interactive game I admire most about is the dark soul series of game, not only for their highly criticized high level of difficulty, but also for the art of 3D medieval dark fantasy in it. With its hardcore difficulty, it points to the future of game as a form sport instead of just a form entertainment. Hidetaka Miyazaki spend over 5 years to create this fantastic game. Hidetaka Miyazaki ‘s Dark Souls creation was inspired by real world architecture such as Milan Cathedral and Château de Chambord, and his previous creation “Demon’s Soul”. To my knowledge the game was sold by the company FormSoftware, and I assume it was developed with commercial software.
