Don't you mean...
Well, one Juggernaut wasn't so terrifying when we had the Colossus, but I will agree that there was that feeling of 'Oh crud, we are so screwed' when 80 of them showed up.
Nope, what he was saying was that the Sathanas didn't project that aura of fear that the Lucifer created, though Kara has pretty efficiently covered the reasons why, and I agree with him, even when 80 Saths appeared on the scene, I still didn't get the same feeling of helplessness and desperation as I did from FS1.
I think in part it's because, in FS1, we were relying on information we didn't even know was going to work, it certainly hadn't done the Ancients any good, and, at the end of the day, only bought half a victory for the newly hatched GTVA, Vasuda Prime was lost, Earth was cut off etc.
I think it may have been a mistake to leave planetary populations out of Freespace 2, part of the 'horror' of that game was knowing that the Lucifer was moving inexorably towards Earth, and when it got there, it would leave it a blasted ruin, even though the destruction was far more wholesale in FS2, it was in a system that there was no real attachment to for the player, saving the Earth, no matter how clichéd it may be, will always be a strong storyline motivator.
