Yes; if you're too slow, it kills off some minor characters who would otherwise survive. The ending to that game is quite well done. It also has you assign NPCs to tasks, and kills a character for each assignment you get wrong, including some non-obvious and unstated requirements, like you can't put someone in charge of a squad if their backstory doesn't mention leadership experience.

However, the early game still has the usual timing incentive problem. Side-quests fall into major and minor categories, and the clock doesn't start ticking until you've done all the major ones.
