Realistic? Yeah impulse took them HOURS to get across Star Systems lol...and I know that's in the ST Universe... but I assume star wars would have an equal...
If they dicked around at every point in a system with 40 orbital bodies, yeah, it did. FTL speeds are nice and fast in Star Wars, but you don't see ships zipping around planets in a few minutes time. The planets are still a small fraction of the size they'd need to be for a realistic relationship with the travel speeds.
I played it until my brain hurt testing out abilities, the pacing is nice. If it needs something, it's quicker start.
