So, I've been running a Starfinder game on my discord server for a while, and with the release of Starfinder Enhanced, I promised to introduce/change some rules to the game to fit what was going on. One rule people were excited for was a potential switch to the 3-action system from Pathfinder 2e.
However, since I did not see any such rules in the Enhanced book, I was wondering if there were any thoughts, ideas, or concerns about switching to the 3-action system. My group has not shown interest in entirely switching to SF2e when it drops, but that system specifically has been asked for.
Well you could make standard actions take 2 actions, move actions take 1, but then you don't have a swift actions taken into account.
Full actions take 3 actions. Which at least in SF taking full action is supposed to block swift actions so that works.
You could add flourish to standard actions and otherwise treat them as a single action, but then you stop someone from making an attack action more than once in a turn, which is obviously probably not the simplification hoped for with adopting the three action economy.
You might be able to take 'most' standard actions that aren't attacks, and make them become two action activity to prevent anyone from being able to do 2 in a round. Then take attacks and make them 1 action be implement MAP method making extra attacks less effective. You'll be making attacks much cheaper action wise however (as normally using a full attack to get extra attacks takes all your other actions away).
You may have to look at the things that are swift actions, as some of them are likely expecting to be only able to be done once per round, and probably expecting to compete for that slot. Maybe you can just get rid of swift actions and make them free actions that you can only do once per round?
Reactions would probably be able to remain similar to how they are.
The hardest part I think would be converting the Standard actions into either two actions, or one action depending on a variety of factors.
to stop distance inflation, you might reduce movement speeds by a small amount so that one attack and two move actions doesn't cause people to fly across maps faster than anticipated.
