I gotta say, I have a pretty tight list on games. I like games with freedom, games that reward and envelop people with open minds, and piloting simulators but amongst the best are:
<X3:Reunion (X and X:2 are great as well), the latest installment in the X series. It is a game in which developers really put their minds to it, and you can do things you didn't imagine were possible on a space simulator. Freedom, freedom, excitement, suspense, choices, ever-changing universe, amazing space dynamics, deep economic system, wide range of jobs/roles, enormous strategy potential, etc. You can stay on your ship as you fight or trade, smuggle or pirate, protect or assasinate. I like being an opportunist and using every feature to my advantage. You can remotely order your property (acquired legally or stolen ships, from which their former pilots ejected, and you can claim as your own) to do anything you want while you either stay aboard your ship or eject and take a spacewalk to other ships or stations, from attacking enemies or defending designated targets to collecting all loot, trading for best buys and sells, making your ships jump to any location you want to aid you or stay safe, get as many real-time monitors on your ships/stations/systems which don't lag your gameplay, get a fleet and blockade the gates to make the system as your own, starve the stations and force them to buy the materials they need from you, or just blow everything up to hell. It is truly a masterpiece, and buying the DVD-ROM version is greatly rewarding, too. If these series were to hit Multiplayer, I'd be amongst the first to buy it. I highly encourage you to get involved in this series, as I am (and still have time for FL :))
