Mhh, KSP will definitely do exactly what the news blurb above lists that BASPM will do. With the exception of historical accuracy
Whether it will go as far as having civilian space traffic, trade, and so on. I don't know. But mods could probably do it when KSP ceases development (ie, is finished) since you can do everything you can dream of with the way KSP was built. Including space combat.
