Okay, yes, there are undoubtedly some weak-minded people who believe what others tell them to believe, including marketers. But as Kurufinwe noted, not everyone who enjoys the game(s) falls into that category. Suggesting that people who do have merely been deluded isn't so much insulting as it is just plain wrong.
That said, Syberia wasn't heavily marketed in any case. If it got good press and word-of-mouth, that's simply because people liked it. Like us.
Anyway, week two has begun! Let the debates rage again!
And hey, look... text adventures!
