Sure. But (until now) that game has been moving within known physical laws.
Yes - laws which don't include relativity, conservation of mass, or conservation of energy. You can have a real-time conversation between people at Beagle Point and in the bubble. You can see ships in supercruise (and sometimes other objects) in places which speed-of-light transmission would mean were impossible. It is possible to agree a single unified timeframe on a galactic basis. Regardless of the speed of light, there's clearly some means to transmit energy at super-luminal speeds between points.
If you want some technobabble explanation, a consistent one would be as follows:
- transmitting matter through hyperspace is increasingly difficult and requires more energy as its mass increases
- transmission distance through hyperspace increases the energy cost but not the travel time
- so transmitting zero-mass particles through hyperspace should be basically free, even over very large distances
- all energy emissions in real space therefore have a much faster hyperspatial equivalent
- our ships and suits sensors are generally tuned to pick up the hyperspatial emissions rather than the real-space ones
- this allows communication and detection (though not travel) to routinely take place at near-enough infinite speeds
