In Ragnarok, gods and demons fought and tore the world apart. In a last ditch effort, the gods sacrifice themselves to create the Grim Angels who put an end to the war and locked the demons away. After the carnage, the power of the gods remained in the holy isle of Riviera. A thousand years pass and the memories of the great war have faded. However, there are signs that the demons are slowly infiltrating the world once more.To counter the impending threat, heroes Ecthel and Ledah venture off in an adventure to prevent the potential destruction of Riviera, aka the Paradise Land. The game is broken up into simple movement, quest, and attack phases. Choose to move by pressing the "B" button and the heroes will automatically move as if the page were being flipped. Arrows delineate where the heroes may move and generally only one path is available per screen. If a treasure chest is encountered in an new area that the heroes have walked into, the Quest mode can be triggered by pressing "A" which allows one of the heroes to open up to chest and plunder its contents.
When an enemy is met, a profile of the creature pops up and it's onto a fairly static adventure-based fight where players choose to attack or use magic/items if applicable. The PSP version of Riviera features voice acting and new graphics and scenes which bolster the overall adventure.
