When you get close to the border of Sirius, it tells you to click M and use the map to select the system you wanna go to. I don't see how it is so hard to miss. Having a map AND a navigation system with auto pilot AND getting pointed to it should make it not too challenging to find a system.
And DC9 is really physically painful. Answering 10 simple Trek questions during the tutorial should be required. Questions like... "If you reroute 23 % of your weapon energy through the defelector dish, will it be enough to enhance your subspace signal to penetrate a tachyon anomaly class 6 and reach a standard relais station 67.9 lightyears from your current position, assuming it will be jammed by 0.8 % by the listening post the signal has to pass 12.2 lightyears away from you, and if not, how much shield energy can you reroute without making your shields too vulnurable to the tetryon emissions in the nebela around you?" Or "What is the first name of Captain Picard?"
