Why there are no black holes in the EEG

I've had a few people ask me why the volumes of the Ephemeris Encyclopedia Galactica don't include things like black holes, pulsars, quasars, nebulae, etc.  The answer is pretty simple.  When we designed the game we wanted it to be as close to hard SF as we could make it.  Yes, we did include hyperspace and yes, all of the species are basically at the same technological level, but those were necessary for the game.  All of the stars listed in each of the volumes are all actual stars, and we've done our best to use what modern science knows about those systems to create planets that might be realistic.  Granted, when we get to the systems that are more than 200 light years away, we're going to have to create some stars because it's a lot harder to see some of those stars (like G and M stars.)
Having said this, as far as science knows, there are no black holes, pulsars, quasars, or nebulae with a couple light years of us...so we didn't include them.  We want the game to be as realistic as possible.
