I'm a sucker for extra features,
so I often run through the downloadable bonus packs, here on gog.
Now, if you're not intersted in wallpapers and such,
you still MUST take a look at the artwork packeges of Syberia I and II.
Holy cow, there are some INCREDIBLE stuff there.
I always respected the tasteful and original art conceptions in these games,
but when I looked at the sketches, plans and scraps provided by gog, literally, my jaw dropped.
Fantastic, FANTASTIC art!
