Simple 2000 Series Vol. 83: The Konchuu Saishuu: Strap on the Birkenstocks, jostle into the hemp shorts, and wander into the wilderness in search of bugs. As the story goes, a whole mess of insects have escaped from a laboratory. Gone. The hapless scientist at the lab charges the player with the task of finding the same bugs that fit the lab's specimen needs. The setting of the game takes place during summer vacation and the player adopts the persona of a boy with a fascination for insects. A rascally blue-haired girl plays the part of a rival that is also collecting specimens for the lab and barging in on your action.

There are over 300 insects that may be hunted and captured in Konchu Saishuu including the popular rhinoceros beetles, grasshoppers, butterflies, and the otherworldly praying mantis. Players wield a net attached to a long stick which swishes through the air to bag all manner of six-legged creatures. Exploratory sessions may take place during the day or night - the time difference changes the types of insects that are out and foraging for food or performing their reproductive rituals. During the day, dragonflies and butterflies wing through the air while evening hours are when stag beetles take flight for their mating forays.

Once an insect is captured, an informative color-coded data card is created which lists the stats and dimensions of the beastie. If the insect has a song or special sound, an audio tidbit may also be listened to. The scientist also holds insect lectures where one may learn more about the creatures that crawl, fly, scamper, and squirm underneath our noses. A VS mode is available where one may pit insects against each other in battling or competitive action. For example, two rhinoceros beetles may joust each other for a thrilling session of Coleoptera conflict.
