I think this is my list:
AC ($5 at G-sale)
ACIII ($23 AZ)
DI GOTY ($8 BB)
RDR GOTY ($20 at BB, but I accidentally bought 2) could use some more GS credit
Last story ($25 at amazon, but they sent me the reprint) could use some more GS credit
NCAA (I just won another copy anyway)
The last 4 are NEW, but I'm not sure I want to bother trying to sell them.
I have a used Smash Bros sitting here that I am thinking about trading in as well. I never opened 'sly', but I think I am going to keep it.
I might trade in B2, since it will have a GOTY anyway.
