I should think we all do... that last thread was started between Genesis and Dragon Song's releases. And I think we've had it at least once since then too, since the textfile I keep of my approximate collection in bbCode for just such threads as these has been updated since my first post in that thread, too. I had to update it again for this version, revealing that I had completely failed to keep meticulous records of my last purchases.
So even though I've manually gone through some of my collection, I'm not sure this is complete, especially since checking my posters is nontrivial.
I did do a partial reorganization of my videogame collection, although I kind of ran out of steam after Lunar, Zelda, Growlanser, and Arc. Photos are here (any questions?):

Posters aren't shown, and some other stuff isn't shown either, like several shirts hanging in my closet, the copy of SSSC which is out on loan, etc. And, of course, some items are simply hidden from view there, like the two watches in boxes hiding behind the one in front, the thin items like flyers, etc. The bundle of stuff on top of the EBC boxes is phonecards and the Genesis screen cleaner. The Nalls are sitting on two more t-shirts. The black things to the left of the main Lunar shelf are mousepads. And some Arc and other WD items are mixed in, mainly in that area. Oh, and the items the, ahem, Special Memories are sitting on were supposed to be sent to G1 months ago. ^^;;;
(The list of things G1 should have from me by now includes:
EB MegaCD, with premium disc etc
TSS guides
Phonecard with Mia 4 bromide
MS/Evangelion folder
SSS double-size flyer

Lemina novel

I didn't add that up. Anyone want to count for me?
(My spreadsheet has, hm, 193 line items, but that's only very vaguely ballpark, as it includes duplicates and a few items given or sold to others, and doesn't include some of my more recent purchases, like flyers.)

Oh, to clarify regarding the original poster's list, I'm quite sure the "not for resale" pendant wasn't a preorder bonus; they weren't used for that. It would more likely have been an early/presskit-type version. Fabric almost certainly not silk, too. There was also only one version of the SSSC guide, so I don't know why the "mini soft-cover version with stickers and such" description. The Sega Freaks cards listed were pack-ins with the MPEG SSS game and the first pressing of the Saturn EB game; I'm not sure from the context of the list whether the MPEG game is part of that person's collection. By "standee" I assume the store counter display is meant, not the EBC pack-ins?
)
and the Ghaleon Puppet which my husband devalued... That was a very sad day. The day one of my friends parents got rid of SSSC was also a very sad day.
