Fun fact: Atari and Tengen are both named after terms from the game of Go, the former describing a group of stones that can be captured [1], the latter the center point of the board [2].
And don't forget Sente Technologies, an arcade game company in the 1980s founded by ex-Atari employees. Sente is also a term from Go -- meaning to be in the strategic position where your opponent will have to respond to your attacks.
