A long time ago I remember playing a fantasy PC game where an old French adventurer is interviewed by a reporter about an expedition he went as a young man. The Reporter then tries to pick up the expedition where he left off.
I used to have a book that had all the flora and fauna of that game (looked pretty cool and plausible in terms of biology). I remember it being based off of a French Comic Strip and a Movie in the 80's
I don't remember much, it had planes powered by floppy disks, villages turned into dictatorships, suicide, assassinations, Giant eggs and white birds with no feet, weird animals and being very difficult to complete at the age of 7.
I know it's not much to go on but that is all I remember, it's been gnawing at me for over 15 years and I still remember the game, I just don't know the name.
