I know Atari is a mixture of a lot of older companies, so why don't they bring some of their older games, that were popular, and put them on XBLA or Wii VC? What they could also do is remake some of their older IPs. For example, Blue Lightning, which only came out on the Lynx and Jaguar CD. They could get a studio to make a new game of that IP, either a realistic game to compete with Ace Combat for the Xbox 360, or a Arcade type shooter for the Wii. Accolade is in there somewhere, which they own Bubsy, that cat thats looks like a rip off of Garfield. They could make a new game out of that IP geared towards kids. Atari Europe(Infogrames Ent.) has a deal with Namco Bandai to distribute some of their games in Europe, why doesn't Atari Inc. do something similar? Wasn't Square Enix looking for some sort of North American partner a little while ago?
These are just some of my ideas. They may not be so good.
