I was looking on GOG.com and becuase i like to spend money, i bought Wing Commander I + II and also Privateer. I played these games loads when i was a kid, someone where i lived had it on their computer and we spent hours after hours on Privateer.
It is a brilliant Game, but when i first played i was reminded of the times where i was blown up within 5 minutes of being in space. and i also was thrown back a decade when i went into the Bar on the starting base and saw the Batender's funny face when he talks to you.
You can get Wing Commander I + II and Privateer for $2.99 each from GOG.com, i highly recommend these because it made me feel young again... younger than my current 17yr old self.
WC I + II page has a link on the Privateer GOG page if your interested.
