Today I replayed the "hidden" True Way trilogy with my fleet and it was an enjoyable experience. The space battles were quite epic, teh story meatier than usual and it had sort of a climax.
I'm talking about the missions Forging Bonds/ The Long Night/ The New Link, "hidden" because you have to talk to Captain Kurland personally to get the initial one and by completion the sequels.
Now I think, itwould be possible not only to remaster these episodes "Stranden in Space"-style, but turn them into a Featured Series.
It would be a quick way to get new content into the game without devoting as many resources as for the other Series.
The basics are already there. Just add some cutscenes, maybe voiceovers (not mandatory), alter the look of Gul Madred and Laas to resemble their alter egos from the show a bit more closely and build them up earlier during the missions so they dont just show up last minute without much lines to speak.
Then all you need is some padding to the story with 2 more in-between missions. One of them possibly another shuttle advanture and another non combat mission, set on DS9 preferably. That station needs some life back. As it is now, Drozana is more interesting than our favourite space station. That's just wrong.
It would also be a great opportunity to open up Cardassian/Bajoran space to the Klingons. It would just about be believable to let them in there as long as they behave themselves and make the station atmosphere that much richer. After all it works on Drozana as well. Think of DS9's episode Way of the Warrior as a template. Was brilliantly done.
