Media management software Plex is expanding into the world of retro video games. For $2.99 per month with a Plex Pass (or $4.99 without), you can tap into Plex Arcade's licensed catalog of Atari titles, including Centipede, Lunar Lander, and Motor Psycho, as well as your own collection of game ROMs and emulators. "The genesis of Plex saw us casting a disdainful eye over shelves of CDs, DVDs, and random files strewn over hard drives; we knew there had to be a better way to centrally organize and curate our media collections," the team wrote in a blog post. "But there was one category left on that media shelf, gathering dust. It was the old plastic cartridges for our beloved gaming consoles of yore."
