The first game on the list is Boktai: The Sun Is in Your Hand; published by Konami and designed by Hideo Kojima. The Sun Is in Your Hand is a unique experience, the game is one of a kind to use some neat tricks that I am going to discuss. The game comes with a built-in clock as well as a solar system, players will have to charge their weapons with solar energy in real life. After the weapons are charged, they can go ahead and slay the vampires they want. Yes, the game uses real-life solar energy to charge weapons, and as the night draws close, the enemies become tougher and tougher. This mechanic makes the game so original, and gives an immersion experience that is found in modern day games.
