Princess Wonder consists of four of the following games:
1. Marionette Kingdom
2. Greedy Kingdoms
3. Love Letter
4. Love Letter to Lady Luck
5. Goita
The first two games are new versions of the existing games by the same designer, Hayato Kisaragi, featuring new art and fixes to the games. All the expansions and promo cards are included in this version.
Love Letter is basically the same as the version the one designed by Seiji Kanai, but the Minister has now been replaced by the Countess from AEG's version. There are three new alternative princesses, each with their own unique power, to create variation to the game.
The 4th game, Love Letter to Lady Luck (LLLL) is the sequel to the widely acclaimed game, Love Letter. As it shares the same background world setting, the art and layout is the same as "Love Letter". However, it plays differently from the original.
Using the cards from Love Letter to Lady Luck, a 5th game, Otome Goita can be played. Otome Goita is based off a traditional Japanese game from the Noto Peninsula, Goita.
