Erik Voskuil, writing for his blog "Before Mario", believes that part of the reason the Color TV-Game series was successful was for its low price point, far cheaper than the competition. He wrote that: "Almost thirty-five years and multiple generations of ever improving, multi-million selling Nintendo video game consoles on, we can reflect on this moment as the beginning of something very, very big." In his 2004 book "Power-Up: How Japanese Video Games Gave the World an Extra Life", Chris Kohler claims that the colorful casing played a part in the systems performing well, saying they resembled toys more than video game consoles. Luke Plunkett of "Kotaku" acknowledged the consoles for their importance as Nintendo's first foray into the market, and for it being influential for their next system. Plunkett agreed with Voskuil in the series being successful for their low price, as it established Nintendo's "consoles must be sold at a profit" attitude that continues today. "PC Magazine"s Benj Edwards that the Color TV-Game 6 and Color TV-Game 15 units in particular gave Nintendo faith in the market due to their commercial success. He also noted that the Block Kuzushi marked the debut of Shigeru Miyamoto, an important figure within the company.
