Input: Consider Input: Question: Which place is older, Chernihiv or Lutsk? Passage:In 1180, Ingvar Yaroslavich joined Ryurik Rostislavich in his struggle against Sviatoslav Vsevolodovich of Chernihiv. According to the Tale of Igor's Campaign, Ingvar was a brave man, however, he never wanted to irritate his powerful neighbors. In 1183, for instance, Ingvar refused to accommodate Vladimir II Yaroslavich in Dorogobuzh, who had been banished from Halych. It appears that Ingvar was wary of Yaroslav Osmomysl, Vladimir Yaroslavich's father. Soon after this, Ingvar took the place of his older brother Vsevolod Yaroslavich as the ruler of Lutsk. In 1202, Ingvar was appointed ruler of Kiev instead of the ousted Ryurik Rostislavich in accordance with a deal between Roman Mstislavich of Halych and Vsevolod the Big Nest, Grand Prince of Vladimir. Ryurik, however, would regain Kiev that same year with the help of the Olgovichs and polovtsy. In 1204, Ingvar took part in capturing the city of Volodymyr-Volyns'kyi together with Alexander of Belz. He was appointed ruler of the city on the spot, but was soon replaced by Alexander due to boyars' discontent. In 1208–1211, Ingvar sent his son to assist Daniil Romanovich in his struggle against the sons of Igor Sviatoslavich of Novhorod-Siverskyi. In 1212, Ingvar and Mstislav Romanovich attacked Vsevolod Sviatoslavich and captured Kiev. After a battle near Belgorod Ingvar voluntarily ceded Kiev to Mstislav Romanovich and left for Lutsk.

Input: Consider Input: Question: Which video game developer who was connected to the Mother series is the oldest? Passage:Mother 3 was originally developed for the Super Famicom (Super Nintendo Entertainment System) beginning in 1994. Shigeru Miyamoto, head of Nintendo Entertainment Analysis & Development and Mother 3 producer, said that Mother 3 was "a commercial decision", since Mother 2 (EarthBound outside Japan) had sold well. By this point, Mother series creator Shigesato Itoi had worked on the series' earlier games and Itoi Shigesato no Bass Tsuri No. 1 and was experienced at pitching video games, so Miyamoto provided a team willingly. The Mother 2 development team carried over to the new game's development, though several people left and the team grew in size. They forewent the usual prototyping phase and went straight into development expecting to create something unprecedented. Itoi said he wanted to make the game like a Hollywood film. In September 1994, he predicted that Mother 3 development would end around 1996 with a release on Nintendo's then-upcoming console. The team was inspired by Super Mario 64 and felt that they too could creatively flourish by making a 3D world without restrictions. Their early technical specifications exceeded the capabilities and memory limits of the platform. About halfway through development, the team attempted to scale back its large scope and changed its development platform to the 64DD, a Nintendo 64 expansion peripheral. At E3 in June 1997, Miyamoto speculated that Mother 3 would be one of the four titles for the then-expected 1998 launch of the Japan-only peripheral, but the game was instead converted to a Nintendo 64 cartridge-only format upon the commercial failure of the repeatedly delayed 64DD.
