Firstly, a definition of character-driven campaign. Derelict, Homesick, Transcend and other fanmade campaigns are a step in this direction relative to FS1 and FS2, where essentially everyone was an anonymous meatbag pilot. But these campaigns were not necessarily character-driven, inasmuch as although they were intriguing and entertaining, the characters served to give commentary and background on the situation, rather than influence and drive it.
I want to make a campaign where the characters are ridiculously important. Transcend and Sync come the closest to what I have in mind, since the player's character does speak and there are fairly detailed inter-character relationships. In my campaign, 2 in every 5 missions would be essentially dialogue, with occasional combat, while the remaining 3 would be more traditional FreeSpace missions. Command briefings would often include emails to and from the player or messages between other important characters. Dialogue would be in a more informal style.
So, would I be asking too much of the player's patience and memory to assign Alphas 1-4 names and identities?

Would you be entertained if, let's say, my dialogue-mission banter was witty enough?
