Hi all, I'm new here. Been in the game industry a long time and currently looking to revive classic Atari arcade games and re-make / re-imagine games like Asteroids, Centipede, Breakout, Missle Command, etc. I've read through this entire thread but I'm still not entirely clear on who owns the IP for those four games I mentioned. Does anyone know? I would love to find out so I can inquire with the current IP owners. Thanks!
