If you had purchased all of these games new when they came out, it would be a huge bargin, but with many of those titles being only good for nostalgic purposes and most just plain not being good, $35 dollars a pop for all of those when you aren't likely to enjoy more than 1/10th of them...
Basically, this set is for a person who wants to collect but hasn't started at all yet and only cares about "having them" and not "having them mint".
