I would have preferred voice over dialogue (with optional subtitles) rather than text. This would have allowed uninterrupted game-play during the campaign missions and I could have helped better tell the story.
When the text dialogue appears it often causes glitches such as locking camera scroll key-presses. The text box was small, and to the side, which felt like it was in the background often going unnoticed, although as it disables controls the game should really be paused or AI disabled or scripted for cut-scenes, and the text could have been made a bit more prominent.
I like the story so far and I look forward to the next chapter, but I felt the campaign levels were a little awkward with the introduction of units with possible unintended situations where some units/buildings were available in the mission prior to their introduction without comment, and some units not available in the mission after they were introduced.
