My mom found my DS games in storage today! I wouldn't value them at more than maybe 20 dollars each, but legit pokemon games run for 60 to 100 dollars each on ebay. It's really scary that a few old games are worth more than a new game console. (Not going to sell them though. I was looking at what it would cost to get White, White 2, and SoulSilver to play. Too much money for me now.)
