I have Shining Force with box and manual/inserts. I'd trade it for the following (basing price off eBay completed sales for similarly complete games vs TCG low, which is roughly equivalent to completed sales for MTG cards):
Lotus Petal - $2.5
Energy Field - $8.25
Enlightened Tutor - $9 (adjusted for condition)
Zur the Enchanter - $8
2x Ancient Tomb - $6.25/ea
$40.25
for
Shining Force (complete in box) - $40
