As anyone rocking a SNES Classic Edition or Sega Genesis Flashback could tell you, retro gaming is big. So big, in fact, that it rakes in hundreds of millions of dollar each year for the video game industry. And the folks at CollectorVision Games certainly are getting a slice of that pixelated pie. Since 2008, the indie developer, which is partly based in the Valley, has released more than 100 homebrew titles (or independently created games designed to mimic the classics) for vintage consoles like the Atari 2600 and ColecoVision, complete with period packaging and manuals. They’ve been a big hit with old-school gamers, especially such popular releases as Ghosts 'n Zombies (a clone of Ghosts 'n Goblins) and Space Raid (an homage to Zaxxon). In more recent years, CollectorVision has put out several titles in its addicting Sydney Hunter series, which are side-scrolling adventures in the vein of Indiana Jones and 8-bit favorites like Castlevania. They’re playable on systems both retro and modern (including the Nintendo Switch) and are bound to give you more nostalgia than an entire season of Stranger Things.
