For those that want to travel back to 1984.
Experience the classic space trading game, Elite, as released on the BBC Model B in 1984, by Ian Bell and David Braben.
From the original box description: "Command your Cobra space ship in a fantastic voyage of discovery and adventure, a supreme test of your combat, navigational and entrepreneurial skills. Trade between countless planets, using the proceeds to equip your ship with heat-seeking missiles, beam lasers and other weapons - corporate states can be approached without risk, but unruly anarchies may be swarming with space pirates. Black market trading can be lucrative but could result in skirmishes with local police and a price on your head!
However you make your money, by fair means or foul, you must blast onwards through space annihilating pirate ships and hostile aliens as you strive to earn your reputation as one of the Elite!"
In general, multimedia content that are always free and available to everyone should be posted in the forums, but if something that was not previously free is offered free temporarily or permanently, it qualifies as a deal. In some cases, decisions on whether a post should stay as a deal or be moved to a forum post is at moderators discretion.
This has been permanently free since 2014 (at least). Original long running deal post.
