First, an important word of warning: If you don't own a decent analogue joystick (and have it ready), don't bother with this game! Keyboard controls exist, but they are totally useless and will prevent any fun from developing. Now that this is off the table, what is Flight Unlimited? How did they attempt to fill the gameplay/goal void which usually plagues civilian flight simulators? First, you have to understand that rather than simulating a regular aircraft, this game is about aerial-acrobatics. If you think looping, you've got the right idea (though that is, of course, not the only maneuver you will perform).
Let's be honest: There are heaps (almost mountains) of winter sports games, and most of them are downhill or slalom races, which play like yet another racing game, in which they simply replaced the car sprite with a ski racer sprite. Actually there might be nothing wrong about it , but to those, who always wished for a more original approach to the alternative winter extreme sports, I want to heartily recommend Ski or Die. There you have to compete in five unusual disciplines (from snowball fight to inner-tube racing) against clock, man and high-score and attempt to make the best impression on the snow fields.
