I came here looking for a game from my childhood
I believe that:
a) It was an early demo I was playing as a child
b) I still have that disc at my parent's house
I'm not really sure why the f- it was even a thing but I came into possession of it sometime around 2003 by buing a brand-new copy of a niche Polish gaming magazine, or so I thought...
After I removed the foil I noticed some things:
- The thick "magazine" was two-pages long with a cardboard inside
- Inside of the cardboard there were 8 (!) CDs
- All of them were from some german gaming magazine dated back to '97-'99
- None of them, including those metioned on the cover were full versions
Other than the Machines i remember playing Half Life 1 (also a demo of a beta version, I think).
I'm worried that ~20-year old disc can be hard if not impossible to read but even if so - I'm gonna keep you updated.
And of course I won't be able to - I can send it by post to anyone willing to perform data recovery on their own.
EDIT: I've just found the post Pisarz was talking about:
Yeah, it is the same demo, the person who wrote it also had it from this shady "gaming magazine". :'D
BTW. I think this topic should be renamed to "Early Alpha/Beta/demo versions" ^^
