I'm writing this review for people who might not know what X-Plane is and may want the opinion of someone who is new to the program.
X-Plane, is of course, a flight sim. It's highly detailed. People say it's the most realistic flight sim ever. Having never flown a plane in real life I cannot attest to that comment, but this program is known to be used by real life pilots for training.
All the DLC in this game is included in that $60 price. You get the whole world... sort of. Not the world as we know it with the unique buildings we all know, but the land masses are very accurate and the airport locations are also very accurate.
The realism, from my perspective playing many different plane sims, is a great place for any pilot to start. There are few variables to change, but they include what kind of damage you can cause the plane through overspeed or over-g. I've seen more brutal flight models in games like Il-2 Sturmovik or Rise of Flight, but I also must bare in mind that those were a different era of planes with their own set of considerations. The damage modeling in X-Plane is not extensive. This isn't a crashing simulator; it's a flight sim. Don't expect to shear your wings off with over speed or any of the extensive modeling you'd find in Rise of Flight. You'll just be greeted with a message accompanied by poorer flight capability.
I do have to make a few comments about the gear I use to play the game.
I have TrackIR, which makes looking around supposedly A LOT easier. A lot of people have to use the hat triggers on their flight sticks and I hear it's not very enjoyable.
I have a Logitech 3D Extreme Pro or whatever it's called. It's got X, Y and Z axes and a slider bar. I can use that flight stick for full plane functionability, though the flight afficianado might want rudder pedals to go with that mix.
My rig is not super powerful: Radeon HD 7770, 16 GB ram and 2.8 GHz x4. The game runs at about 30 to 40 FPS with dips into 28+ sometimes. It's not optimal for this program. I would suggest something better than what I have.
It's mainly fun for me because I can make my own objectives within the simulation, though it doesn't have the premade missions that FSX had. You can also play it like a rogue-like if you want to. For example, try to make your way going North up to the very northern tip of Alaska using airports as "save" points as a sort of no save scumming/ironman challenge. The plus side to this is that the routes you can take are so varied that you will probably not see the same scenery twice.
I say that I recommend it because you can do what I do and cruise your local airports and have a lot of fun trying to get more proficient at flying. You can pretend that the time spent in this program is actually training you to operate planes. Whether or not that is helpful to you is a matter of opinion and situation.
