Stepping back into this because I remembered an issue that hasn't been discussed (Patrick briefly touched on it but barely).
It's not a case of releasing Palpatine or not releasing him; time spent developing Palpatine could be spent on developing something else.
But why is it more important to spend time developing someone else other than one of the main badies from the entire saga (thus far)?
I could easily say time spent developing something else could be time not spent developing Palpatine. That doesn't make it right.
This is more to counteract claims of "saying you don't want Palpatine in the game is selfish because you're taking it away from everyone else" (not actually quoting); the reason I and others don't want the time spent on him is we'd find him immersion breaking.
I know I've read the threads but I'm in the camp saying it wouldn't be, especially based on a CANNON book Lords of the Sith.
