The heroine of this curiously named title is Choko, the princess of the fictional country Baskin, which is mostly a medieval world with some modern-day anachronisms. She lives in the capital city Robins with her Mom and Dad, namely queen and king. Her curious nature eventually leads her to some interesting acquaintances, including magic users and adventurers, who help her to uncover a threat to her family and country. The princess has to travel through a dangerous forest with her best buddy Meron, in order to protect Baskin from danger. 31... is a Japanese-style adventure game. The interaction is minimal, usually restricted to two or three commands (mostly Look or Talk) with a few sub-menus at most. Usually, the player advances the story and proceeds automatically when all the options at the screen are depleted. However, there is also menu-based navigation (in the forest, etc.), which requires memorizing ways and choosing directions correctly. The game contains scenes with nudity and sexual situations.

Chōkōsō Crisis is an example of a hentai Breakout variant. The plot involves a faraway planet sunken in corruption and sexual crimes; young girls have been kidnapped and are about to fall victims to terrible experiments. An ordinary young boy names Kenjirou is assigned with the task to travel to the building where the girls are kept, and to liberate them. To do that, he first needs to - logically - destroy layers of bricks with a ball! The player controls Kenjirou in person, his head adorned by a construction worker hat. Kenjirou runs left and right, hitting the ball with his head, hands, or feet (controlled simply by letting the ball fall at the appropriate angle). The bricks come in different colors; red ones are destroyed in one hit, blue ones require two, etc. Higher levels feature more complex brick systems, and more tough-to-break bricks. Kenjirou has limited lives, and the game is over when he lets the ball hit the floor too many times, losing all of them. Some bricks produce power-ups when destroyed; these include additional time for Kenjirou to finish the level, slowing down the ball, etc. Every level is an erotic picture obscured by the bricks and unclear colors. Once all the bricks have been destroyed, the picture becomes clear, and a sex scene follows, after which the hero ascends to the next floor, continue his perilous quest for demolition and carnal pleasure.

Hayate: The Battle is set in the same universe and features the characters from Jikū Sōsakan: Hayate. Unlike its predecessor, it is not story-driven and focuses entirely on battles. In the first game, all the fights were dictated by the story, and the obligatory player-controlled character was Hayate himself. In Hayate: The Battle, the player can choose any of the characters from the previous game, male and female. The battle mode allows the player to choose the opponent as well; it also has a two-player mode. The tournament mode allows the player to choose the playable character, but not the opponents. The game introduces the opponents by itself, increasing the difficulty as the battles progress. After the player has won a battle, a scene with nudity and sexual content is displayed (those scenes do not have a connection with the story). There are adjustable difficulty levels as well.

This game probably has one of the most disturing game intros I've seen on the PC-98, and the rest of the game follows the intro rather well. It's an adventure game that really is almost a visual novel, with only a couple of binary choices for you to make. You date on of two girls, and frequently, get horrifically killed by some knife wielding nut in the endings.

Female college student is found beheaded. Kamiya Ukyou will hold investigation again. Third work in the series and first of four works of serious nature. As always, real case is taken as the basis and this time even investigation is based on real one. Case is held with all the formalities and real impediments, so it's the first work using "True theory". While year 1993 became one that allowed extreme H-scenes and CG, year 1994 became first year to allow extreme gore CG. In this work backgrounds are using live-photo, but characters are same anime-like.

Jubei is a high school student who comes from a shaman family of shrine protectors. The shrines hold the barrier between this world and Makai. One day the barrier gets breached and closest people to Jubei get attacked by a monster. I was actually very impressed by the game. Great music, fascinating story, fast-pace development, bright colors, wide use of animation. I only regret of not being able to finish it as pc-98 version gets stuck shortly after switch to last diskette.
