I first started playing FS, ...
I had the demo for FS2, it came in bundle in a graphics card box that my cousin left me (new card for the pc). And the art of the disk looked cool, and then the intro movies kinda had me sold on the game.
Training was good, and then I just kept playing, and playing, and playing. Until I bought FS1 atleast 3 yrs later, and FS2 1.5 yrs after that. (and FSOpen 6 months after that). And here I am today (nearly 1 year after getting FS2).
Movies/Cutscenes... I blame them

-------------
Playing the full FS2 was a great relief though, I didnt think it could have expanded like it did. And that Sath rammed me pretty hard the first time... scared me sh*tless... (considering it jumped from 1/2 loaded to the 3rd "DIVE" nearly instantly...)
