I agree, and again anecdotally I found the same to be true when I was a kid at school. At most you had a few sub-groups, like the guys who were into Transformers, and the guys into GI Joe. We were not a sophisticated bunch, but then as you pointed out, our brains were still larval. When Lunchables came out, we all wanted them. From my recollection we didn’t even like the taste, we just wanted them.

There was some variation, but it was all on a predictable theme.
