Hope all goes well for you and your family. Good news is; you can fairly quickly get liquid in the games, priced a tad on the lower side. The bad news is; there are a lot of us "Buyers" who have $$$ invested in new titles coming soon.
I own 3 of the 6 games (and additionally MMr Black when it arrives)... my opinion on approx. values are as follows;
AC/DC prem (clear window) ~$6,000
MMr $??? This will depend on trim color reviews and overall reviews in the next couple months. I wouldn't open the box. Are you considering selling your place now or your game when it arrives?
