Abandonware

I recently fell in love with old school sifi movies again with my favourites being Alien and the Predator, naturally bringing me to Alien Vs Predator. And from movies cae the games which led me to discover that what could be objectively the best avp game of them all avp 2. Is all but impossible to obtain. Anywhere. GOG has avp1 and steam has avp(2010) but nowhere on the internet is it possible to legally purchase the game without going into the clutches of the second hand market and combatting the corrosion of disc media. Strangely this game is too young to emulate yet too old to be available as a classic. However there was hope for me as a small community kept this game alive through patches and free publically available iso files and installers, aswell as multiplayer servers. This game is beloved enough to have 16k votes on the gog community wishlist. But yet we still have to rely on patch installers and unpacking iso files. What other games and software that lay abandoned could the high seas of the internet save?

tldr; piracy saves abandonded games and software, whats your favourite? discuss.
