I keep bringing it up, but Atari is also currently working with WB on a Mortal Kombat compilation, meaning that they have a working relationship. Announcement of this Namco collab DLC for Atari 50 opens doors for other collabs, and that's where working with WB creates opportunities. I can envision two separate DLCs:
>Williams and Midway home ports (Defender, Stargate, Joust, Robotron 2084, Wizard of Wor, Tapper, Rampage, Xenophobe, etc.)
>Atari Games arcade company after 1984 (Marble Madness, Paperboy, Gauntlet, RoadBlasters, Tetris (if deity Henk Rogers approves), Hard Drivin', S.T.U.N. Runner, Klax, Pit-Fighter, Rampart, etc.)
