*Highly recommended titles: Street Fighter IV and Phoenix Wright.
"Five cases from the original game are included, and each case should take you a few hours to go through depending on how quickly you read or how much you goof up in court. Phoenix Wright is an insane value at its launch price of $4.99, as when it first launched on the DS it was the kind of game you couldn't find anywhere in stock, and when you did, it was at least $40.00 because of how rare it was."

While for Street Fighter IV, it's the best case to prove skeptics wrong that such games won't work on iPhone. Everyone who bought the game loves it (see Appstore customer reviews) and even many hardcore SF4 fans from the console counterparts admit the port is great and stays true to the game - from the game mechanism to the look & feel.
SFIV on iphone cannot compare to owning it on a pc/console with a proper joystick setup. Just keep that in mind.
