Part of what separates flight sims from arcade flyers is the control options. At the simplest extreme, one has a stick to control flight and the opposite pole has a landing tower, radar and flap angle indicators.
Sky Odyssey uses every bit of the PlayStation controller, but in a way I found intuitive. The left analog stick controls the up/down orientation of your plane's nose, and tilts the wings. L1 and R1 buttons affect the left and right rudder, and are used to go left or right without tilting the wing. The X and Square buttons control throttle, and the other buttons are used for things like landing gear or dumping fuel. 80% of the time, you'll work with the throttle and some combination of the left analog stick or shoulder buttons. Aerodynamics are accurately represented in
Sky Odyssey to the extent that a tilt to the wings will cause the plane to 'slip' down in the direction of the lower wing, and many other neat tricks can be performed by mastering the relationships between tilt, pitch, yaw and airspeed. Many in-flight displays are available, but all can be turned off. Mostly, things like radar show the lay of the land or location of landing strips and objectives, but the speedometer comes in handy, too.
Managing the items you collect with a plane is done in the main menu between episodes of play, and each plane earns its own collection of items. From time to time, you'll get special items. When you decide to upgrade or modify a plane, you'll look at the available parts in each category (e.g. wing, tail, body, etc.) and by scrolling through, see the effect any item will have on your plane. I didn't have a real problem finishing the game with a single plane, but it took serious customization at times. Another neat option in Sky Odyssey is controlling the weather. In certain modes, you are given the chance to choose what weather you'll be flying in, and the interface is set up to look like a real-life weather map, with high- and low-pressure areas visible along with storm fronts. By dialing the clock to different settings, you watch patterns move along the map until you see conditions right for flying. All levels in Adventure Mode are preset, so it's fun to go back and fly areas you've visited in storms when the sun is shining again later in Free Flight.
Sky Odyssey had me hooked from the moment I popped it in and started playing. There's enough training available to have even the greenest pilot up and flying quickly, but seasoned gamers or sim fans won't be bored. For a game whose only violent element is a wrecked plane, Sky Odyssey has more going for it than any flight-combat game I've ever played, and so-called 'adventure' games could take a page out of this book when designing gameplay. Kudos to Activision for this great game; Sky Odyssey is one of the most unique experiences available right now for PlayStation 2.
