Field hockey is a widely played team sport of the hockey family. The game can be played on grass, watered turf, artificial turf or synthetic field, as well as an indoor boarded surface. Each team plays with ten field players and a goalkeeper. Players commonly use sticks made out of wood, carbon fibre, fibre glass or a combination of carbon fibre and fibre glass in different quantities (with the higher carbon fibre stick being more expensive and less likely to break) to hit a round, hard, plastic hockey ball. The length of the hockey stick is based on the player’s individual height, the top of the stick usually comes to the players hip, taller players typically have taller sticks. The sticks have a round side and a flat side only the flat face of the stick is allowed to be used, if the other side is used it results in a foul. Goalies often have a different kind of stick, however they can also use an ordinary field hockey stick. The specific goal-keeping sticks have another curve at the end of the stick, this is to give them more surface area to save the ball. The uniform consists of shin guards, shoes, shorts or a skirt, a mouthguard and a jersey.
In 1996, the Tamagotchi was released, created by Akihiro Yokoi, Aki Maita and Takeichi Hongo. The Tamagotchi was one of the inspirations for the first release of the Digimon franchise, a device marketed in June 1997 with the name Digimon, a short for Digital Monster. Aiming at the male audience and created by Akiyoshi Hongo (a pseudonym that refers to the creators of Tamagotchi), this device shows to players a virtual pet composed entirely of data and designed to play and fight. In February 1998, the DigiMon fighting game, compatible with Windows 95 and developed by Rapture Technologies, Inc. , was announced. The one-shot manga C’mon Digimon, designed by Tenya Yabuno, was published in the Japanese magazine V-Jump by Shueisha in 1997.
