(re: What are the odds?) Yes, Syberia is probubly the closest to the old Sierra games as far as the way the story was done and the amount of little hints they hid around. I have almost all the Dreamcatcher games and you are right, they are all missing something that was present in Sierra games. The later Nancy Drew games do come close to old Sierra as well but some of the earler ones had a poor engine. Ovcourse I am a Gk, Kq and Lsl fan and I am aftaid no one will ever make a game as good as they were.
Another game I was very sad to see go was the Tex Murphy Sierries thanks to good old Microsoft. Ha ,Ha
I would love to see all the folks at Sierra start up again even if it had to be under a different name and I would be waiting in line to get there new games like a lot of others, I bet.
