I agree with this wholeheartedly. Megaman Battle Network 6 had some things I could do in post-game, but I didn't want to do any of them because simply walking around town had intense "shit is happening" music. Half the no-function NPCs weren't there, and the certain things were there (guess I won't spoil it) that wouldn't normally be in a relaxing post-game setting. I love being able to do things post-game, but part of the fun in that is that you don't have to stress over the main story and can just cruise around doing fun side-quests.
