I've actually been sitting on an X bundle I bought a while back and have all the games up till now. After seeing the Rebirth trailer I decided to get into it.. so I'm actually playing the very first X game to just burn through the story.
I'm surprised how into it I am for such an ancient game and asking myself why I didn't take the plunge sooner. I guess it's always been just that.. "Here's a ship, now off you go!" factor that's seemed too daunting. Didn't take long to get the hang of the game though.
And yeah, I didn't expect the economy to be dynamic like it is in this early a game, but the universe is trading goods without my intervening.
I was a little dissapointed to follow a freighter through a jump gate and not see it on the other side, so some things are being spawned on the fly... at least they stay persistant within the sector. Kinda neat to see the Pheonix roaming around that first sector you start in.
Kamikazi Xenon are not fun though (I know they fixed that behaviour in X2).
