Microsoft Flight Simulator X is the perfect flight simulator, guaranteed to take you on a journey sky-high.
Bad graphics aside, this game has actually created its own gamer community. Everywhere you look you will find FSX forums, user designed plane skins, add-on packs, gamer reviews (like this one), and so much more it is just mind boggling. That really shows the power of a game like this one, which so many people have come to know and love.
I really like this game probably because of the escapism. Its a great way to be able to fly your own plane, even when plane tickets are so expensive. This game is also designed to be user-customizable, so you can make it whatever way you like. Landing on the highways and smashing cars does get old after a few hours, but the customizable air, sea, and land traffic provides many opportunities to turn a real-life simulator into a video game.(If only the planes had guns...)
Whatever your purpose of playing this game, I would recommend it to everyone. I didn't even know how to fly when I bought this game, and now I am a pro (by my standards!). So, this game is pretty cool, and a great way to pass the time (and destroy cars).
