Silliness vs Seriousness, How much is too much? Options

[Shaddow]

So, I'm writing a game that is rather silly in dialogue and overall plot, but I still plan to make it a full game with seriousness happening. I like to think that I have a good balance to it, but that leads to my question.

How far can you go in silliness in a game before it becomes a silly game and loses all credit?

I think something like Bleach or Disgaea is perfect.

A perfectly serious plot is great. But if you want silliness, don't be afraid to add in a clever quest or dialogue that will make the player chuckle or something.
