"You can't enter alpha family numbers or damage amounts, for example, but you're not prevented from crashing the game with extravagantly large values."
Why not? IIRC the value that kills SE4 is pretty well-defined. I'm having a hard time figuring out why Users wanting to have SE4 friendly files precludes preventing values that crash SE4
Values that don't DO anything are another story, since they can have usefullness in their own way..
