Mike,
You're right- but some of them are so "real"- I can't help but think "yeah, I want to be challenged; I want it to be "real"- but I can't take 3 weeks off from my life to get good at it!
I just purchased the Falcon 4.0 this summer and I kinda gave up on it because I had to go make my actual life. And because the wife and kids were out of town, I did have plenty of free time!
It is amazing how far the graphics, etc have come in ten years. It still amazes me that the MS Flight Sim will put you at any airport and it will look generically the same but with boxy buildings, etc.
OA
