collection comparisons for trading?

[ugr]

This would require a little bit of coding, but hopefully it wouldn't require a revamp to existing site code. Anyway, I was thinking...

I'd love to be able to trade games with others on the site, but the wishlist/for sale thing is something that my brain doesn't do. I think of putting things up for sale as separating them out, putting them in a bin or box or somewhere that designates them for sale, etc.

But like, what if there were a quick script that would just look at two collections, see what each person has more than one copy of, and then see if it exists in the other person's collection? if it doesn't, it would suggest it as a possible trade for the same thing but a match in the other direction? or it could just make a list. "this person has two of the following games but you don't have them", that sort of a thing.

Along a similar line, I also thought it might be neat to do something silly like collection battles, for example people could put their collections up against eachother and it would battle out their collection "Person 2 won the NES battle!" "Person 1 won the PS2 battle!" etc.

Anyhow, thanks for reading!

I see collection folder was something private i won't trade/sell.
Having 2 in some game doesn't mean i have to copies, at lest for me, for example, some old portuguese imported games have 2 instructions, the portuguese and the imported one, and i just mark 2 in quantitie when i have both or 1 if only one.

The things i could trade &sell is for that folder ...

It could be nice to have a script that identifies the user's that have more games in the whislist, for example you have found a user that want 15 games of your list.
