Hey Gamers,
I have been in this situation more than once. The college student's need for cash is ever looming over our shoulders. If you find yourself pinched for cash, look through that library of games you own and part with one or two that you have either completed completely or one you are not fond of playing anymore, or just one you could do without.
Head off to your nearest GameStop or talk to a friend who has your system and see if he/she would be interested in taking it off your hands for a fair price.
