Without going into speculation, I seem to remember Infogrames got their start on the Amiga platform. Wow, the irony here is great.
Speculation time:
I suspect BBRV isn't thinking of the AtariST, which we remember long wars about.. We must also remember the history of both the Amiga and Atari are very much intertwined. At one point Atari was supposed to purchase the rights to the original Amiga instead of Commodore. Jay Miner designed much of the pre-Amiga Atari stuff. Atari was one of the handful of "founders" of the home computer market.
I still think I like using the name Pegasos though....
