Apparently Major John Plaster has been deeply involved in the design of a sim/game detailing SOG missions...

To be honest I was pretty surprised by this. I've read all of Plaster's books and he's a great story teller but I have a hard time imagining these being recreated in a compelling manner virtually. Especially as SOG missions seemed to involve getting in and out with no contact...
If interested, here's the website...though there's not a whole lot here.
