Nettō! Gekitō! Quiz-tō!! (熱闘! 激闘! クイズ島!!, Hot Fighting! Fierce Fighting! Quiz Island!!) is a quiz arcade game that was released by Namco in 1993 only in Japan; it runs on the company's NA-2 hardware, and is the tenth title from them which allows scores that do not end in "0". It is also the second game from the company for which a knowledge of all three Japanese writing systems (Hiragana, Katakana, and Kanji) is essential if players wish to succeed with it (the first was Bakuretsu Quiz Ma-Q Dai Bōken, which had been released in the previous year - but it only allowed two players to play simultaneously). The players must help four characters called Kufū (工夫), Hana No Sei (花の精), Koseibutsugakusha (古生物学者) and Nōfu (農夫) regain control of an island, by answering multiple-choice questions (like what Scott and Stanley had to do to regain the crown's lost jewels in Bakuretsu Quiz); each of the characters starts out in one of the four corners of the island and conquers a square once they have cleared its stage. They can then decide which square they want to move to next, by pressing one of the Answer Buttons - and if one character moves onto another one's conquered square it will invoke a special type of quiz, in which the conquered square's owner will set the trespasser eight questions (and there shall be a keyword that is common to all eight answers). If the trespasser answers all eight questions correctly he (or she, in the case of Hana No Sei) will take possession of the square; but if they should get one wrong, the owner will send the trespasser back to their last conquered square. If there are less than four players, four characters named Chisogin Bob (地底人ボブ), Ringu (リング), Makoto (まこと) and Pochi (ポチ) shall fill in for the missing ones (until they have been defeated) - and most of the stages have four-answer questions, but there are also ones that have picture questions, ones with only two and three answers, ones of four different genres, ones that players shall receive twice the usual time bonus for answering, and ones that will decrease the required number of correct answers by one before they start. Once all thirty-six squares on the island have been conquered by the last surviving player, the final boss, Chitei Daimao (地底大魔王) shall emerge from underneath the island for the first time in 300 years (meaning that the last time he did it would have been in 1693); he has three different phases, and each time the last surviving player answers all eight questions in one phase correctly, he will change colour (in the case of the third phase, he will explode, much like all the animal opponents in the game do when defeated). The player will then be treated to the unique ending sequence of his or her character - however, unlike in Exvania, all four of them have good endings.
