The wacky unpredictability of whether or not I can make it through a routine flight without FSX crashing keeps it VERY interesting for me. That...and the endless problem I have had with FSX over 4 different PCs that I can maintain an excellent framerate until going on final keeps me on my toes.
Sorry for the sarcasm...I just got a gaming laptop a couple of months ago and despite the fact that it can play everything I've thrown at it flawlessly with great detail and stability EXCEPT FSX has me endlessly frustrated.
Still awaiting a great next-gen sim...I'm calling FSX a complete failure after over 10 years and 5 gaming pcs/laptops. Just poorly written I'm afraid...bad graphics engine.
