I dunno, personally if i where in his spot i would be kinda desperate to actually find someone who would take over such a huge project and keep it running (instead of , as someone said, take the keys and then have a big slamming auction) that i would let go of any "personal requirements" on the new owners.
Will it be better then if he finds no one because of his high expectations and then be forced to close up shop due to health issues/age anyway? Then he will be forced to either let those games sit and rot in his warehouse because he is stubborn or have that dreaded big auction.
