These are my favourite DS games:
Top of the list are the Ace Attorney (Phoenix Wright) and Professor Layton series.
I love good old click & point adventures, which is why I really like Secret Files: Tunguska.
Art Academy is a great painting "game". I was never personally interested in painting and thought I'd completely suck at it, but when I gave Art Academy a try I was really astonished by myself what great pictures I could paint after just 2-3 hours of Art Academy.
Picross is a really great game too, Very addictive.
