Atari seems to be on a bit of a spree recently to make something of a big gaming comeback and they recently announced even more acquisitions. Not only do they now own Nightdive Studios, they also recently swallowed up the AtariAge community too!
More recently though they put out word that they've taken over multiple titles from Ronimo Games including Awesomenauts and Swords & Soldiers. Both slightly odd purchases, since neither seem to actually have an active player-base any more (at least going by Steam numbers) but they must have a plan for their future.
Also just announced is that Atari has purchased Digital Eclipse, a developer who works on various re-releases using their proprietary Eclipse Engine. So think of them like another Nightdive Studios, as Atari clearly see a lot of promise in updating and re-releasing older games (and in many cases those do sell very well).
