Tried out
Syberia (the first one) today, but didn't get very far due to the graphics glitching when I Alt+Tabbed out of the game. Had to close the game, and didn't feel like relaunching right away.
I've played
Syberia 2 in the past (don't have it installed at the moment), and got seriously stuck fairly early on. Should really continue trying to figure that out at some point...
All in all, haven't had much luck with the
Syberia series.
Liked what little I've seen of them, though.
