Curious on site info

If this isn't the right place for this post I apologize. I can find lots of information here about what to do with a game collection one already owns, but what about information relevant to buying decisions? What I mean is that I can look up, for example any scenario in Kokoda Trail and find out what I need to play it.

What I can't find is a tree that tells me something such as, "If you buy The Young Lions, you'll find 100 scenarios. 23 are playable with what's in the box. 35 need Streetcar Named Desire. 12 need Le Mans, Around the World in 80 Days. 18 need Tweaking Legions, The Prisoner Episode #21, and Krull. 9 need Bastone, Gumby: Day of Doom, and Road to Berlin. 2 need every PG game and and supplement ever published by Avalanche Press. 1 needs every game and supplement ever published by Avalanche Press and something else, but we're confident no one will get that far."

Is there a chart like that available? Thanks.
