Got an email that a new MapPack that includes Falklands battles and a few new ships is now available for $20. Looking at it, other than the map, I don't see much of a point.
I am playing Steam and Iron non-stop right now and really don't see the point of Jutland and DG except as references for setting up new ships and scenarios in S&I.
By the way, the release has sparked a deluge (3 actually) new messages on the SES forums. Mostly negative, but even there biggest fanboi/mod doesn't have good things to say.
