I would agree. There were two Queen Airs done in the sim world. One was a 2002 sim model by a Japanese builder the other was Mike Stones Queen Air 2002 then 2004(for which there is an FSX Conversion) but alas none had a VC so you have to use the 2D panel. I don't fly sim models with 2D panels so I have left them alone. There are several of these early Beech's that have never really made into the simulation world but they were all good aeroplanes, the Beech Travelair, the Twin Bonanza (yes there is one but it is well very dated), the Duchess, the Queen Airs (A65, 65 and 70). Curiously in OZ the Queen Air was well liked and was the backbone of the light commuter airline market, air freight and the RFDS for years and were quite common for a long time. I have flown them all and the Queen Air was a nice solid aeroplane with no vices that got along at a good clip. What I always like about Beechcraft was the fact that you could move from the Bonanza to the Duchess, to the Queen Air etc and they were all basically similar in the cockpit area in way that made them all feel comfortable like an old shoe.
Can't see anyone doing one though not for FSX which is a shame. The closest thing around is the BE99 by Premier Aircraft Design, I fly that one occasionally and it is not bad either, and there are some mods etc around to make it quite presentable, it has a good interior as well, cargo and passenger.
