Buyers will be able to redownload purchased copies of After Burner Climax at a later date, but once the game is delisted, it can no longer be bought or added to a user's software library. Sega Nerds speculates that expired licensing agreements between Sega and the manufacturers of the real-world aircraft featured in After Burner Climax are to blame for the game's forthcoming removal. A similar issue resulted in the deletion of Sega's Ferrari-licensed racer OutRun Online Arcade from digital storefronts in 2011.
Starting next year, if you want to legally play After Burner Climax and don't already own a digital copy, you'll need to track down an original arcade machine. Here's a tip: The GameWorks across the street from the Washington State Convention Center in Seattle hosts a pair of Climax cabinets, so you might want to make plans to visit the next time you're in town for PAX Prime.
