IGN Ratings for Microsoft Flight Simulator X: Acceleration (PC)
out of 10
PresentationExcellent aircraft choice, fun new missions and a competitive multiplayer format add a lot to the game.
GraphicsIt's still one of the best-looking games on the market. The new assets are nicely integrated into the existing game.
SoundGood radio chatter and sound effects. Music is enjoyable.
GameplayThe new missions offer a nice range of challenges. Online air races seem fun but seem a too predictable by comparison.
Lasting AppealLoads of content and online options definitely help extend the life of the original game.
OVERALL(out of 10 / not an average)
We also had the front page of GameSpot (http://www.gamespot.com/pc/index.html?navclk=pc) on Monday but looks like they moved on to another title. However they do have a page with lots of goodies (videos, wallpapers,...) at: http://www.gamespot.com/pc/sim/flightsimulatorxadrenaline/index.html?tag=result;title;1
