Trade In values

I have $25 to spend, not enough for a decent DS game. Which one of these games should I trade in.

Mario Kart

NSMB

EBA

Metroid:Prime Hunters

M&L: Partners in Time

Super Mario 64 DS

or Children of Mana

The older the game the less trading value u get for it. So if u want to trade any of your games trade the one that have been release within a year, you'll get more then if u trade in the older games.

I'd just save up some money and then buy a game.Djammal86
