The graphics are good, but all the systems look much the same. If you play this game you will understand why the good ones don't put too much emphasis on the physics. Ponderous and glacially paced. Of the twenty or so systems I've discovered, 15 don't buy or sell anything. I'm trying to build a ship but it needs resources for the project to begin. I go get them but when I return to the shipyard, they can't afford to buy them off me. What the? Entering combat makes your ship almost unflyable. Joysticks are a must. Dont waste your time or money on this. There are many good Space Sims but this isn't one of them.
