H4 was the only one I owned (sold it for an obscene amount on eBay shortly after 3E was released).T. Foster said:The problem (at least for me) is that the H series modules just aren't very good. I remember (and it's been ~20 years so I'm foggy on the exact details) H4 as being particularly rancid.
In fact, if I made this poll about what people owned then I'm sure the votes would be higher. I owned a lot of the classic adventures but never used them (mostly because they were higher level than we ever were). This includes classics like the GDQ series.
