I have finally gone through my entire collection and cut it down by about 80%. I have created a google spreadsheet document that lists all the games I have available for sale. There is also a selection of random games listed on their own sheet in the document that represent my original "for sale" items that were leftover duplicates and otherwise unwanted stuff and such from when I was still collecting. I'm keeping them apart from the others for documentation purposes.
The following is a google docs link to everything available. Filters are provided and I gave a very rough grade with explanation for the primary components of each item. If you are unfamiliar with docs, in order to use the filters you need to click on "Data" --> "Filter views..." --> "Create new temporary filter view" and then the dropdowns will become active.
SpaceFlea's Collection
NOTE: Some people have missed that there are multiple tabs (delineated by company). Make sure you check out ALL of the tabs. They should be listed at the bottom of the spreadsheet.
Items listed under #N = New; #U = Used. Under the condition columns N = Not Present. I had those queries before, so I thought I'd calrify up front. I took pictures of all sealed NES and SNES games, and can distribute them and/or take others upon request. If you request a large number of items (say 20+), please provide an offer.
