Advise: Organizing a huge class

Alright experts - I’d love to hear what you think on this:

I am making a game right now and so far I’ve done a pretty good job of encapsulating without taking it too far…

I have one class that I’ve entitled “Hero.as”

This class has TONS of properties… on top of all the properties I already have to make the class work, now I have to add all of the “attribute” properties (i.e., defense, hit points, agility, luck, etc.)… there are about 15 additional properties that I am about to add.

Also, I am splitting up the game into levels which will all live in their very own swf files… in other words, one swf per level. These swf files will pass the properties back and forth depending on the level chosen by the player.

So here is my question: would it be wise to make a separate class called HeroProperties that does nothing but store all of the attribute properties? It would keep things a little more organized, but I may be taking things a bit far. Does anyone else get nervous when their classes start getting really big?

Thanks,
AR
