Other guy gave an okey explanation, but to try my hand at explaining:
On a typical round of combat, you get three actions. You can spend them in a variety of ways. An attack is one action, movement (“stride” action) is one action, most offensive spells are 2 actions, etc.
A lot of classes get ways to “discount” actions. For example an early feat fighters and barbarians can take is “Sudden Charge” which let’s them stride twice and attack an adjacent creature and costs 2 actions.
The whole thing lends so much freedom and takes a lot of burden off the DM for needing to homebrew / make up things on the fly. The whole system is very crunchy though (very detailed and particular on its rules) and so doesn’t fit everyone’s vibes.
You have three actions that you can spend freely on attacking, moving around, etc. If you want to attack more than once, you get a penalty on the roll.
Some things and spells cost two actions.
At least fading suns had something similar in the 90’s with one action for free, 2actions with a - 4 and 3 actions a - 6(if my memory is right). The interesting part is that dodging would count as an action and you had to declare your intention at the start of the round.
Out of curiosity, what is the 3 action system?
I know FATE has 4 actions (overcome, attack, defend, create an advantage) so did PF merge attack and defend? Or is it a different choice?
