I'm not sure I agree with this. Yes, GW at one time had lots of 'bit part" figures, but the size of the catalog is pretty immense, particularly for 40k.

How many unit types are open to Chaos Marines today? Space Marines?

I have mixed thoughts about this. On the one hand, you get a lot more options, but it conversely stifles creativity since instead of kit-bashing you just use the pre-molded stuff.
