I find this "everyone should thank System 3" talk quite hypocritical. After all it took them years to release the game and apparently for more than a decade they didn't care about the people who were interested in the game. It's good that the game got released but that still doesn't mean people have to bootlick them! If someone wants to thank them, fine, but it is also OK not to do so as it should be one's own decision how to react to the fact the game is finally out.
As for thumbs on Pouet for the crack intro, yes, most probably more than 16 people have watched it but often there won't be any comments if something is not extraordinarily good (or bad) so people watch it and move on. It always has been like this and this is not an "Amiga only" phenomenon.
