Stated somewhere is a rule that you can either have everything hit on a natural 20, or require it to be an actual hit. I align myself more with the idea that you actually need to have the correct bonuses in order to hit; that sometimes, even when luck is in your favour, your opponent will always outmatch you. 

Players' Manual p204 wrote:

ATTACK ROLL: A d20 roll that determines whether an attack hits or misses. Almost every combatant has a chance to strike his opponent. Many attack rolls are modified by attributes such as strength and dexterity (see VOL. I, ATTRIBUTES), special abilities, sorcery, and other factors. N.B.: If the referee deems it appropriate, all “natural 20” rolls automatically hit, and all “natural 1” rolls automatically miss.

That's it!
