I'm just browsing through the units and checking them out. The Zealot is my all-time favourite SC unit, partly because of the outstanding voice/lines he had in the first game. I was a bit disappointed with how they've changed him now, sounds a lot more "blurry" and a lot less aggressive.
It's nothing much, don't start flaming now, but it will take some time getting used to, SC had perfect voice characters and effects, hopefully they will live up. It seems that sound and voice get overlooked, but I think they are just as important as graphics.
I was a bit iffy over the drop-ship taking the sound-clips straight from the Aliens film. Although it did fit well, it felt a bit like a short-cut, I mean they didn't even clean up the samples that much (from the sound of it anyway)
