The Ace Attorneys see you thinking laterally and piecing together clues. I guess to fully enjoy it you need to get onto the story and enjoy solving mysteries. There is no action scenes so perhaps you would find the gameplay lacking but there is a demo available online that Capcom did, its the first trial of the fourth game. Give it a shot, you can decide if the series is worth your time without spending money or bending the law - http://www.court-records.net/gs4demo.htm

Scribblenauts doesn't involve any drawing. You type the objects in with an on screen keyboard and manipulate them with the game's character. ^_^

And Yoshis Island 2 is every bit as good as the first game and then some. The one problem is the screen sizes on the DS, (not its resolution), so it might be nicer on a big 3DS.
