Actually, playing Chinatown Wars is challenging enough with the stock stylus. I opted to get smudgy, using nimble finger pokes to guide my way around the pint-sized Liberty City. These chopstick-style styli are going to remain unused. That way, when I give them away in a future swag-laden contest, they'll still be mint in package. Paper sleeve. Whatever.
Definitely the best styli since the Legend of Zelda: Phantom Hourglass feather. Far less regrettable than the Pac Pix one I spent good money on via eBay. (And no MSG!)
