Dedicated fans are powerful forces. A super-fan will collect every commercial product of an imaginary character because they enjoy the break from their normal everyday reality.
This video is a combination of a few other videos made about Magical Girl Lyrical Nanoha. Interestingly, we never actually see Nanoha Takamachi in the video. Instead we see someone wielding all the weapons and powers that Nanoha possesses in the show.
This is the allure of video games of popular imaginary heroes. People want to be the hero for a time. Experience the extraordinary.
Normal video games allow you to play the character on the screen. Augmented reality will give the oppertunity to “be” the character on the screen. The company that does that will bring to legions of fans to the technology.
