I’ve just stumbled across Abandonia, a repository of abandoned games that are available for your downloadable amusement.
They’ve got such classics as 4D Sports Boxing, Abuse, Alien Breed, Alone In The Dark 1 and 2, Another World, Archon, Arkanoid, Barbarian 2, Battle Chess, Cadaver, California Games, Crusader: No Remorse, Dark Seed 1 and 2, Dungeon Master, Eye Of The Beholder, Flashback, Gods, It Came From The Desert, Jagged Alliance, Karateka, The Lurking Horror, Narco Police, Powermonger, Prince Of Persia, Shadow Of The Comet, Star T rek, [X-Wing](http://www.abandonia.com/games/375/download/StarWarsXWingCollectorsEd ition.htm), Stronghold, Syndicate, UFO, [Ultima Underworld](http://www.abandonia.com/games/193/download/UltimaUnderworldStygia nAbyss.htm), Veil Of Darkness, and the complete Sierra Police and Space quest series.
There are loads more titles on there. You’ll almost certainly come across your favourites. I’ve just stumbled across BloodNet - I missed it the first time I went through the list!
Warning: Downloading and playing these games will almost certainly destroy the great memories you have of them. Only attempt to get them to run if you’re confident that your blissful nostalgia will come to no harm! Having said that, some of these actually hold up quite well…
Enjoy.
