I would love to see you add the ability to customize race dialog from within the game.
For example, the program would prompt you with: "we have claimed all these Precursor Relics for ourselves"
The player types in, "Patience child, knowledge of the ancients is for the old. Knowledge of the Precursors and their relics is ours to steward."
This would allow a lot of customization, hopefully with only a few more ascii fields in the faction record. I'm sure it is more difficult than that, but it would be nice.
