The "simulation" is too long & tedious. Why would anyone need to simulate flying to another star system? Interstellar space is not a tunnel and it's not filled with rocks. Why does the map show you're in a new place if all you did was a simulation? The story does not indicate an acutal flight took place. Nobody actually used cryotube and set the ship's autopilot to fly there. There's barely ever enough room to not get hit, so all it the dodge tunnel does is act like a unwelcome grind to prevent the player from playing by wasting their time.
