Real Racing is without doubt the slickest racer yet seen on the iPad. It's not the quite the prettiest, but the small sacrifice in detail is more than rewarded by a smooth and consistent frame rate, something of a holy grail for driving games which require fast reactions.

With the next update, available when iOS 4.2 hits, Real Racing will support online multiplayer via Apple's Game Center.

• The new online multiplayer mode joins the comprehensive line-up of existing Real Racing HD features, including:
• 6 game modes: Career Mode, Time Trial, Quick Race, local multiplayer, online multiplayer and online Leagues.
• Massive career mode with 76 events. Players can unlock 48 cars in four classes by winning races.
• 12 stunning unique tracks set in city, forest or desert environments.
• Game Center achievements and leaderboards (achievements and leaderboards also available without Game Center).
• Touch or tilt to steer, manual or automatic acceleration and braking.
• iPad exclusive "car-skins" – wrap an image from your photo library around your car
• iPad exclusive “ghost racing”

Game Center is starting to look like a very useful addition to iOS.
