If you have to liquidate your collection you would probably have to sell all them games kinda a dire situation, also not to mention that allot of the games that are some of your favourites while not always expensive sell pretty well wich is another factor you will most likely not end up with all your favourite games if you don;t have to sell everything that is, 100 games is still a big amount to keep after a liquidation, I would personally think 10 - 20 max games is a more suitable number to keep after a liquidation.
