Just paid off my house last spring and did it without selling anything out of the 75 pin collection, now granted I sold approximately 550 other pins but you can't keep them all, right? Refinancing the house was the key to it. Not to mention a few bucks off of those games helped too. I guess it depends on what you want more, debt free house with no games or a collection of nice games with a mortgage payment. The choice is yours.
