The current list:
1. Graded Video Games
2. Trading Card Games
3. Graded Action Figures
4. Trading Cards (Character or Sports)
5. Graded VHS Tapes
I wish Heritage, specifically, would break out the first two into their own domains. I really don't care and there's a lot of news generated by those categories. I'm sure it's great fun to collect both of those things and I knew some people who did art for MTG in specific, so I appreciate what it means to people, but… I just don't care personally. If they were moved into their own domain and their own marketing list, I'd be much happier with my Heritage experience. Considering that there are plenty of collectors who only collect comics or original comic art, I don't know how many people are buying an Action #252 and (Rob Googles "expensive Magic Cards") a Mox Emerald (Alpha.)
And don't even get me started on the CGC emails congratulating themselves on their card grading prowess. Spoiler: I let my paid membership lapse.
