I played RQ3 back in the 1980-ies. I remember running Apple Lane and Trollpak. I also remember the PCs all died when they attacked a Dream Dragon on their way to Pavis.
I returned to Glorantha with the new edition and ran a play-by-forum game for awhile. We ran through the Apple Lane scenario of the Gamemaster Screen Pack, and I was hooked.
Having found five interested players I've now decided to start a new tabletop campaign. We will play by the new rules, but I've decided to run the old Borderlands campaign set in 1615. As some of the players are new to rpg:s and almost all are new to Glorantha I decided to reduce the number of variables and make them all Sartarite exiles from the Red Cow clan. They will be siblings or cousins, and we will generate their family history together when we meet for our first session tomorrow.
I decided on the Red Cow to leave open the remote possibility of having the PCs eventually return to their homeland to run through the Eleven Lights campaign. The probability of the campaign lasting that long is low, but one can dream.
The campaign starts ten years earlier than the standard RQ:G-campaign, so I had to rewrite parts of the family history section. With help from the BRP forums and some Glorantha blogs I added events for earlier years. I also decided to replace the personal skill bonuses with added language skills, in order to make the characters be able to communicate in Prax.
My plan for the first session is a short intro talk about Glorantha (bronze age, runes, gods etc) and Runequest (skills, deadly, etc) followed by Daine's Briefing. After any questions, we'll do the actual character creation. That might take the entire evening, we'll see.
I use Kanka.io to store my information. I've also prepared a Discord server. At the first session we will talk about our attitude to online activities between game sessions.
