There is currently a bit of a lack of new games for the Nintendo DS while non launch titles are being finished. So I took a chance and got Sega's Sonic Team collection of semi abstract weird wacky mini-games called Feel the Magic XY/XX. I know it sounds like a weird Japanese Dating Sim game but it really isn't.
This is a interesting bunch of mini games that are designed using the pen and touchscreen. In fact there are no controls using the buttons and digital pad in them. The art style of the game has a unique look to it. The colors are bright but the people are black silhouette that look like the people in the iPod ads. The story is roughly based on a guy in japan who has a crush on a cute girl and he joins a group of abstract street performance artists called the Rub Rabbits in order to get her attention and save her from various wacky situations. The games that really come to mind are Incredible Crisis on PSOne, Warioware on the GBA .
The games include painting, yelling at the microphone, blowing on the touchscreen to blow out candles and unbuttoning the girls dress after you are drying off next to a beach fire. I have no idea why this got a Teen rating considering there is no nudity, swearing, blood, violence. It does have implied getting naked by a fire so it got a Teen rating but I really can't find anything that I wouldn't want a kid to play.
Sonic Team has a special place in my heart so I was thought it would be worth a shot. The mini-games are fun and pretty interesting but I don't know about it's long term replay appeal. There are some unlockable dresses and hair styles by sticking in a Sega GBA game into the DS before booting up the game. This is not Final Fantasy 7 and it is not Half Life 2 but it is a decent Warioware like game to hold you over until the selection of DS games picks up.

You can also unlock various outfits by clicking on hidden hotspots in each of the pre-game "intro" cut scenes. There are "hidden bunnies" in there. It was definitely an interesting experience--I was afraid I was going to ruin my DS with some of the games, though.
Don't know that it will be quite enough to "hold you over until the selection of games picks up" . . . ungh. Such cool hardware, and nothing to do with it.
