Quoted from CrazyLevi:
Imagic made killer stuff, their games always looked and sounded so good. I loved Atlantis and Cosmic Ark.
I had a huge collection of Atari stuff I picked up for pennies at mid 1990s yard sales, and sold it all on Ebay around 20 years ago. Like 250 games and a 7800.
Wish I'd kept it all of course, would be fun to play from time to time.
They made a gazillion of them, and they are not as collectible as early Nintendo.
If you see Nintendo Cartridges at a yard sale. BUY THEM.
If you see anything that comes on a cartridge with a box, BUY THEM.
If you see anything in a sealed box that comes on a cartridge, BUY THEM.
Random loose Super Nintendo and NES games go for 20ish bucks on ebay. Games with boxes go for hundreds more often than not because EVERYONE threw the box away. The boxes for some are way more valuable than the cartridges. Almost nothing was left sealed.
Found a box of Pinball related NES games with boxes at an estate sale I was too late to get the pinball machine from (some douche showed up the night before the sale with cash and took it to flip). I made over $800 selling pinball related NES games from a single estate sale because they had boxes. I think I paid $10 for them. I make good money at my day job but I'll buy to sell Nintendo games when I see them because they are worth your time.
Loose atari cartidges? Maybe $5
