Thanks to fatwallet, my wallet just got a little bit lighter.
Was planning to get the Yoshi's Island 2 DS as part of the deal, but Sharon suggested to get the Pokemon Diamond game instead.
Thinking that the portable Pokemon games have quite a good resale pricing, i grabbed it along with a game that i've been eyeing for a long time, Trauma Center, where you use the DS stylus and its touch screen to perform operations and stuffs.
The freebie in this deal, Custom Robo Arena, is a (i think) role-playing game with lots of customization. Again it's one of the games that was on my list.
