First generation of video game consoles
This was also the first involvement of Nintendo in video games. According to Martin Picard in the "International Journal of Computer Game Research": "in 1971, Nintendo had -- even before the marketing of the first home console in the United States -- an alliance with the American pioneer Magnavox to develop and produce optoelectronic guns for the Odyssey (released in 1972), since it was similar to what Nintendo was able to offer in the Japanese toy market in 1970s".
Viva Piñata: Pocket Paradise
Back in 2005, Electronic Gaming Monthly reported that Rare was hard at work on two projects for the Nintendo DS. Their first Nintendo DS game released was "Diddy Kong Racing DS", so that game and "Viva Piñata" were most likely the two projects mentioned.
