Okay. This seems to demonstrate where the problem just begins to happen.
ENGINE: 0% slider, 67% complete
GAMEPLAY: 50% slider, 95% complete
STORY/QUEST: 100% slider, 100% complete
The assumption I'm making is that I should generally target my 0%/50%/100% ratio on my sliders.
Which is better: Cutting an engine component (Savegame) and getting my engine to 100%, or leaving Savegame and Multiplayer in and leaving my engine at 67%?
Gameplay has another choice: Do I raise my gameplay slider past 50% to reach 100% complete, or is leaving it at 95% complete better, or is removing a component (gamepad or mouse) going to be better? (Which also raises the question of gamepad on a PC or mouse on a gameling).
So there are some very specific questions. My more general question was "How bad is it for something like the engine to be at 67%? Is it important to cut components to reach 100%?"
