Wagan Land (ワギャンランド Wagyan Rando) is a platform game series released produced by Namco (now Namco Bandai Games) that has been sold exclusively in Japan. The seven initial games in the series were released for the Family Computer, Game Gear, and Super Famicom from 1989 throughout 1994. Some of the games were re-released in later years for mobile phones and on the Wii Virtual Console. An eighth installment for the Nintendo DS was released in 2009.
The series stars Wagan, a mysterious creature resembling a green mechanical dinosaur who must protect his homeland of Wagan Land from the mad scientist Dr. Devil. The games features standard side-scrolling stages where the player must reach the goal, as well as boss encounter where the player must compete in a mini-game such as concentration and shiritori. The character of Wagan was previously introduced by Namco in a 1987 amusement game for the arcades.
