roughly 685 NES games with 90% going on ebay for a buck with 1 or 2 bucks for combined shipping, you might be able to buy 99% of the games with 6k. it's like when you're collecting cards...you open 100 packs to find 99% of the set, but you have to open at least 100 more to find those last couple cards you're missing, wishing you had paid the lousy dollar for the missing cards.
