Its a shame you don't receive the animated introduction to Creatures 1 as part of the install. I havn't yet played any of the others in the series, so I don't know if they have intros too...

Could this not be supplied as a downloadable extra?

I have yet to buy it myself but does the GoG.com version of C1 come with the old tutorial video? If not, people can check it out here:
