What is a simulation? According to the imaginary dictionary I keep on my desk next to my imaginary bust of R. Ready to discover once-and-for-all whether X-Plane is better than FSX? Whether Falcon 4.0 is better than Milk Float Simulator 2012? Ready to read the word 'realism' 46 times in a single hour, and spit feathers on discovering that the sim that caused got you through your divorce has been cruelly cold-shouldered by an idiot with a bus fetish and a sci-fi blindspot the size of the Crab Nebula? You are? Splendid.
