Mitsumete Knight is a dating simulation game produced inconjunction by Konami and Red Company (of Sakura Wars fame, and now named Red Entertainment). It was released in 1998 for the PlayStation. The characters of the game was designed by Takenami Hideyuki who had previously taken part in designs for Sakura Taisen, and specifically, enemy designs for Sakura Taisen 2. The game itself was modified from Tokimeki Memorial: Forever with You, with improvements including an expanded area to display backgrounds and larger characters. It should be noted however that the gameplay between the two series varies in many areas.

In Mitsumete Knight, you are a young man who is sent to the fictional medieval country of Dolphan, where you must train to become a Holy Knight and to defend the country from attacks by the neighboring state Valpha. But as you arrive at Dolphan, your interest is shifted towards the pretty local girls. Will you be valiant in your training, or will you spend your time trying to have a date?

This is essentially a "dating-sim" game with elements of RPG. You have a schedule and have to decide what to do in order to charm the girl of your dreams. Various activities increase your skills, and it's important to remember which girl will be impressed by a particular skill. In addition, you also have hit points and gain levels, just like in a traditional RPG. Sometimes you'll be attacked by the knights from Valpha or other enemies, which will result in battles. The outcome of such battles largely depends on your previous training.

Much similar to Tokimeki Memorial, on which the game's programming is based, the player chooses one of several options to spend his weekdays and Saturday on, with war-related tasks such as sword training or horseback riding. Other non-combat related options are available too such as grooming, studying and resting. On Sundays, the player can choose to find any one of the girls the player has met and arrange for a date on any following Sunday. Alternatively, the weekend can be spent on the usual trainings. There are periodical sword fighting, horseback riding and beauty competitions to award outstanding stats of the player and to impress the characters. Different titles are given to the player according to the strengths or weaknesses. A second part of the game lies in fighting the war for Dolphan. One of the ten generals of the opposing country will challenge at different times, with about six fights in total. The player will have to fight the general in a simple RPG-like real-time battle. Failure will not result in a game over, nor alter the outcome of the war per se, but the player will be hospitalized for a full week. If the player wins all of the battles, he will receive an honorary title from the king at the very end, and such is the requirement to finishing the game with one of the main characters, the princess Priscilla.
