I think about this and im wondering how much a blessing VTT is? I got used to 3E/PF1 through decades of play. Then again, it never hurts to offload that part of the game no matter how second nature its become.
I am a very lazy DM. I don't prep in advance almost entirely and my players and I collaboratively build the world as we go using "Solo DM engines" such as an oracle die to make up the story as we go. I could never run PF2e this way without a VTT i'd assume (I haven't tried to be fair) but having all the resources for the system so easily available that it is merely a matter of "drag & drop" to create an encounter as we need it makes PF2 actually come alive as a system.
All the nitty gritty is hidden behind the automation and intuitive interface.
Example of play:
We just go with our gut feeling and say: "Ok this is a dungeon with undead in there, there might be a witch as well or some sort of necromancer."
We ask the oracle die: "is something bad happening?", roll a d6, the answer is a 1 (yes).
We ask: "Is it severe?" roll a d6, the answer is 6 (very).
I open the Bestiary and type in "flesh golem" because I think that's what a necromancer witch type of villain would have, I find "Zombie Flesh Golem", one is level 3 one is level 4. (I also have a tool that I can easily adjust the monsters level to what ever level i'd like it to be with one mouse click according to the stat rules)
Nice, we want an encounter that is Extreme (I like to have a challenge, btw I also have a character in the game, I DM and play at the same time), as per the encounter building rules we choose the level 4 Zombie Flesh Golem version for an Extreme+ encounter for our 3 player party.
Ok next thing I do is drag & drop the monster on my randomly generated dungeon that I imported with one mouseclick into my VTT from here:
One Page Dungeon by watabou
The party (our characters that don't have the meta knowledge) gets scared hearing something big stomping towards them quickly so they try to run, back to the exit they roped into.
We ask the oracle die: "Is the escape going as planned?" roll a d6, answer is (2) No
We roll a portent (2 random words) i.e. "unexpected" "blocked", oh naughty word.
We ask: "Did somebody cut our rope?" roll a d6, (5) yes.
Ok now we have to fight, the Zombie Golem is charging towards us. We throw some marbles on the floor and hold a rope with 2 PCs behind the door so we trip whatever big thing is coming.
We roll some checks with a few mouseclicks, the Golem trips as it bursts into the room, nice! We get some free attacks in.
Add everyone to the Combat Tracker roll initiative for everyone including the golem, takes about 10 seconds to set it all up, start the combat
Now we are in what PF2e arguably does best, the combat mini-game, everything is automated, every feat and ability we use is one click away, drag and drop style for effects we might need to indicate that someone is raising a shield while we mark the Golem as being prone giving it all the negative modifiers it would get automatically.
We can fully focus on playing the combat mini game now, actually not having to worry about the nitty gritty allows us to do cool stuff and we don't get paralyzed by it. We actually trap the golem in a fire trap door (cool stuff like this doesn't exist in PF2e right, cuz everything is codified, well we do it without even sweating it) every rule we need can be referenced quickly to keep the encounter in line with the mechanics, what is not in there we find a quick ruling for.
After 30min of detailed combat we have defeated the Zombie Golem almost getting TPKed. 30min is a lot? Not if it's fun. We enjoy every second of our 6s simulated combat turns.
Combat is over, we add XP to the sheet. Healing checks for recovery no problem a few clicks. Mark a few +10 minutes steps on the World Clock to indicate that we have been taking the "treat wounds" action, roll a d6 to see if we get ambushed while doing that (cuz you know, we like to live on the edge) (3) not this time, we live to fight another day.
Get back into exploration mode, click a few buttons to drag and drop the exploration activity indicators on all our PCs so we know what each of us is doing "within the ruleset" while we roleplay our next steps.
Ok, now I forgot why I started writing all this, but I guess it was because I wanted to showcase what automation can actually do for you. Zero prep, and with a bit of time invested in learning how to set up and access these things, it will save you much time in the long run, and actually lets you run the games you always wanted to run. Combat like a detailed simulation, but without bogging you down in the nitty gritty while still allowing you to add in all your own ideas and rulings, it's flexible.
I am a lazy DM by nature, I don't prep, I was told PF2 doesn't work this way, for me it does, otherwise I wouldn't play it. I am thankful for all the guys that codify this and import all the rules and assets. Also thanks to Paizo for allowing everyone to freely use their stuff! What a time to be alive.
PS: Disclaimer: No spell checking, commas and so on, I have to go to bed and wanted to get this written down. Thanks for understanding.
