Did you find Syberia 2 as much of a disappointment as I did? It was okay while I was playing it, but it lacked the spirit of the first and the ending was, in its own way, even less satisfying that Syberia's.
Imo Syberia can easily stand on its own the way it is, without the sequel. The ending is beautiful and keeps up the mystery of the game.
I find Syberia 2 is worse mainly because Kate no longer changes throughout the journey the way she does in the first game... and Hans Voralberg turns out to be a pretty disappointing character. It could've been more interesting if something was actually done with the subplot concerning the private detective that is sent after Kate, instead of the few boring cutscenes.
That said, though, Syberia 2 has more creative puzzles, and the landscapes are breathtaking. Supposedly there're plans to make a Syberia 3... let's see how that goes.
