Iris Online is a prime example, utilizing a Tarot-based set of mechanics that tie 22 dungeons of the game to the 22 Major Arcana and allow players to change into monsters via a card system. Gala-Net is opening the game up for beta testing registration, with the game's testing set to commence at an unspecified time in the future.
Described as a gypsy-themed fantasy game, the aesthetics feature a surfeit of bright colors and surreal imagery, such as the accordion-legged horses seen in the title image. (Those are mounts, for the record.) It also sticks to the Tarot theme in its dungeon mechanics -- the Lovers dungeon, for instance, may only be entered by a male character and a female character, both of whom must survive together. While the details on gameplay are yet to be fully revealed, Iris Online certainly has a unique look to it, and those interested can sign up for beta testing now.
