If i trade in pure,ninja gaiden 2,stranglehold,army of 2,and wanted how much will gamestop give or trade in 4?

They probably will give u 10 - 15 dollars depending how clean the games are and i remember where i traded in like 6 of my games and i only got like 30 bucks but the problem about that is i traded in like a whole bunch of new games so that tells you how cheap gamestop is.
