If I were you, I'd simply access Google Group, type the name of the game wanting information on in the exact phrase box, perhaps the OS in the all box, click the down-arrow off to the right for Sort by relevance and select Sort by date, search, and see what others are saying.
Is there any forum on CZET that answers questions about adventure games or are all the forums for technical issues?
I have a couple of game sites links but most of the time they merely suggest walkthroughs while my questions are many times of a more technical nature.
