Sounds an awful lot like the X series of games. X3 Terran Conflict isn't particularly difficult to start out with, and has everything you mentioned.Must have joystick & cockpits, must have shiney shippes, must have long upgrade path and wide range of difficulty in different places, must have trading mining & loot.
Personally, I want a game like Freespace 2. Just a pure fighter-pilot-in-a-war game, no trading or mining required and instead have an extensive, awesome campaign.
