its intersting to me the drastic difference of games where the box and manuals are not worth anything. while other times the cart is worthless while the complete game is worth a ton.I sold lots of valuable games over the years and lately prices of complete games are way up looking at my old transactions years back I sold a mint godzilla 2 complete for 75. and little samson mint cart for 95.00 lol the good old days. I just found a mint copy of baseball stars 2 for the Nes I posted it on the forum actually. the cart sells 20.00 all day loose. yet mint complete box and manual it sells for a max of 50 usually 30 to 40.  Is it the newer release games this tends to happen with? seems that way.
