Digital Eclipse wrote a quick FAQ on their website: https://www.digitaleclipse.com/media/digital-eclipse-atari
Most important (I think):
Is Digital Eclipse only allowed to work on Atari properties now?
It is business as usual at Digital Eclipse! While we’re certainly happy to have greater access to Atari’s fantastic library, we still have the freedom to seek out projects with other parties. In addition to recent releases like Wizardry: Proving Grounds of the Mad Overlord and The Making of Karateka, Digital Eclipse has a lot of unannounced projects in the works that do not involve Atari’s IP, and those will carry on as planned. The future is wide open, and we believe partnering with Atari will bring about even more opportunities.
Atari? You mean Infogrames?
♫ Oh, those Infogrames!
Oh, those Infogrames!
Wears Atari like a pelt
and buys up all they see! ♫
During their fiscal year meeting (May 2009), IESA announced that it would be changing its corporate name to an Atari branded name, in line with the use of the name for its subsidiaries. In reference to this, Atari, Inc.'s CEO Jim Wilson said: “We’ve gotten rid of the Infogrames and Atari duality, the confusion around that. We are one simplified company, under one management team, under one brand.” https://en.wikipedia.org/wiki/Atari_SA#Rebranding_to_Atari_SA_(2009–2013)
Modern Atari is not Atari. Its Infogrames with stolen valor.
