Legend of Eldean is the first Albert Odyssey title to be released in English, as well as the first to feature traditional turn-based role-playing elements as opposed to tactical, strategy-based gameplay. It was created as a "gaiden", or sidestory to the original titles, and contains back story, characters, and plot that are independent from earlier games in the series. The North American version received mixed reviews.

Albert Odyssey: Legend of Eldean is a traditional RPG, with an overhead perspective and combat based around the selecting of character actions from menus

Slayers Royal (スレイヤーズろいやる) is a 1997 RPG by Onion Egg for the Sega Saturn, based upon the Slayers anime series. It was followed by Slayers Royal 2.

Slayers Royal (スレイヤーズろいやる, Sureiyāzu roiyaru) is a 1997 tactical role-playing game developed by Onion Egg and published by Kadokawa Shoten and Entertainment Software Publishing only in Japan. It was originally released for the Sega Saturn on July 25, 1997, and its PlayStation port by Japan Art Media was released on April 23, 1998. Slayers Royal was the third video game adaptation on the Slayers franchise and the first that featured the full motion video cut scenes and voice actors from the anime versions. This well-received game was followed by a non-sequel Slayers Royal 2 in 1998.

Contrary to its two purely role-playing predecessors in the comedy fantasy franchise Slayers video game entries, Royal is a tactical RPG. The game is split between Adventure Mode and Battle Mode:

• Adventure Mode itself has two components, conversation and travel (including visiting in-town locations such as stores and inns as well as dungeons). There is also no free movement while exploring the dungeons and the progress instead depends on the player's story choices.
• Battle Mode features an isometric-view perspective similar to this used in Final Fantasy Tactics and is round-based for selecting orders (including a variety of spells and character-specific special moves), followed by their execution ending with a next turn. Each character in the player's party can be controlled either manually or automatically by AI. The fights can take place outdoors and indoors, and the most powerful offensive spells (such as the ultimate "Dragon Slave", capable of destroying large parts of scenery) can not be used in the latter.

Compared to the previous Slayers games, the use of CD-ROM as media enabled addition of FMV cutscenes and a large amount of digitized voice sampling, featuring the voices of Megumi Hayashibara, Maria Kawamura, Yasunori Matsumoto, Masami Suzuki, Hikaru Midorikawa and other main actors from Slayers anime productions. The PlayStation has some new features such as an improved FMV quality, five minigames (such as "Slayers Quiz"), and the DualShock controller vibration feedback compatibility.
