I am also learning that VTT play tends to be much more front loaded than I'm used to. It takes a lot to get things set up but it sustains play longer with minimal effort at upkeep. I'm liking it a lot so far.
Agreed. I found that after running 5E on FG for years I have so much prep material that it makes running games really simple. What I found most useful was things like prepped flexible encounters, i.e. various CR rated groups like bandits, mercenaries, orcs, etc that I could pull out in second and put on a map and use them for a dozen different uses (town guards, assassination squad, random encounter, etc). That and then having ready maps to pull from when I need something on the spur of the moment.
Since (general) you are here, what does your prep actually look like (some of you have answered this already)?
So above is a lot for D&D 5E. Though I have to add I often would go to bed thinking about how the various factions should react to the current situation and then over the next few days taking notes on that.
But, for FrontierSpace my prep looks like;
A lot of setting building. It's pretty open and without a lot of detail or lore so I've been creating a lot of that. Giving it to the players though Message of the Days stories when they log in. Some are told like news casts, I've got a running series I call Five on the Frontier that are five topics of a paragraph each on current event (ship crashes on planet x, riots on planet y) and others might be stories heard at a lounge or tavern (the pirate ship Odelion, etc).
Maps, I spend a lot of time creating custom maps. Not a fan of most maps I find online, though I do spend time looking at various Patreons and sources. 90% of the maps I use I create myself via Campaign Cartographer.
I've also spent time creating factions and fleshing out those that are mentioned in the rulebooks. Such as the Asimaar Prelacy has mention of historical purges of psychics centuries ago so how does that manifest today (i.e. riots and persecution and limited trade with required permits for ships being able to enter restricted space, etc.
And part of that is creating flexible things like a set of building guards so if they try to break in to something I have a ready set group of NPCs. Even some detailed locations so when they step into a bar on some planet I have a list of NPCs I can put in with descriptions and names.
And I've been writing background on locations for the parties adventures. I don't count most of this towards prep, because I may spend 4 hours of prep for outlining enough for the players adventure on a newly discovered planet, but then 40 hours fleshing that out to actually have enough detail to publish it.
