Interesting question. I put together my collection based on games I like, and I get them into the condition I like. At this point there are few games I want more than the ones I have, so I'm not sure that a little more money is much of a draw. Any offer would have to take into account market value, for example maybe $3k more than I paid is the replacement cost, which would give zero incentive to sell my favorite game. If an offer was $3k above market, that does make things interesting.
