The World Ends With You - In my opion DS GoTY, buy it. (I have a review @
gDoo - by Trent Petronaitis )
Assasins Creed DS - an alright game imo
N+ - I wouldn't but it when you can get it a free pc version. But yeah I'll consider it depending if it is good or not
The other games I'm not interested or Japanese games I havn't looked into yet.
