Bloody Roar 3 pits 12 outlandish combatants against each other in one of the most ambitious 3D fighting games to grace the PlayStation 2. Returning from Hudson's widely acclaimed PS1 titles are Stun, Long and Jenny, each of who brings a unique fighting skill to the arena. During each bout, players build an energy bar based on the number of successful kicks and punches they land on their opponent. As the bar fills, players can then morph their combatant into terrifying manimals from beasts such as lions and tigers to moles. The morph, in turn, unlocks a secondary control system specifically designed with each creature's combat moves and appearance in mind. In effect, this offers players two distinct combat types within one game.

Bubblegum Crash is a PC Engine graphic adventure game based on the anime OVA series of the same name. The anime/game is set in the near future of 2032, which has seen Tokyo split into two by a massive earthquake. Corporations rule the country, production-line humanoid robots named "boomers" are being used by villains to commit crimes, and the beleaguered police are too under-budgeted and incompetent to handle it all. The all-female mercenary team the Knight Sabers, who use powerful exosuits called "Hard Suits", are the city's best defense. The game operates similarly to other adventure games of the era. The player is given a selection of commands that they can use to interact with the world, including talking to NPCs, picking up and using objects in their inventory and moving to other areas. At any time the player can look and listen for extra context clues. The commands are in English, but the game's story and dialogue text is entirely Japanese. The game will occasionally switch protagonists, starting with Nene Romanova and moving to Priss, Linna and Sylia at various points.

Case: Titanic is based on the manga and anime Silent Möbius. It presents an original episode that involves the sighting of a strange ship in the clouds above Tokyo. Closer inspection reveals that the ship appears to be identical to the famous RMS Titanic that sank in the Atlantic Ocean in 1912. The game's nameless male protagonist boards the ship along with Rally, Kiddy, Nami and other heroines from the manga in order to investigate this seemingly inexplicable phenomenon. The gameplay is done in Japanese-style, puzzle-less adventure format. The entire game is set on the Titanic. The player is generally free to visit various areas of the ship in any order, though access to certain locations is restricted and necessary events must be triggered in order to gain it. The commands Look, Talk and Move are used on most screens, and there is no inventory management.
