Greetings from Munich. (Wet and windy, just like home...).
Just to add a bit more to my explanation above, kindly pasted here by Austin, you need to remember that Creators Forum is the "test bed" for new things. Over the years, members of CF have helped to test potential changes to vessels, potential missions and so on. The feedback that they have provided has been most useful and has had a major influence of the development of the vessels.
When VSTEP and I sat down to work out the release schedule for the Super Packs, it was intended that we would just release the content from Creators Forum. But when I started to collect it all together, I realised that with some extra work we could get new lights, new horn sounds, new radio packs and so on. Also, LucAT and I had continued working on the vessel dynamics and controls, so we had a lot of extras.
In the end I decided that pretty much everything in the Super Packs would be new and original. I then asked a team of selected Mission Creators (Artship, Des Healey, Hugh Gammon, Matt, SadSid and Terry - oh, that's me) to write some brand new missions for this. - They have done a really excellent job with very tight timescales, so thanks, chaps!
So, here you are!
