Runequest 6 by Design Mechanism and Guide to Glorantha by a kickstarter campaign have woken up quite a bit of activity for Glorantha.
RQ6 is excellent ruleset for the game masters and the most fun edition of RQ so far. It has two excellent scenario books already out – Book of Quests and Monster Island both of which can be set on any universe. Monster Island especially is a magnificent tome for the GMs.
RQ6 is still missing the Glorantha parts that are coming in Adventures in Glorantha later. For those that can’t wait there are at least two fan efforts to bide you thru
Progressive spells for RQ6 by Bruce Mason and a collection of the Gloranthan spells for RQ6 by Gloranphile
I found also the following quick reference tables created by Gloranphile very useful.
Lately a fellow Finn skoll has created excellent enemy editor at . He has been quite responsive to feedback either on the Google+ community page for the Design Mechanism or at Design Mechanism forums
There is active Glorantha community page at Google+ with lots of old timers but many new faces as well.
There is an update to this old post from August 12, 2013. Gloranphile graciously approved now (January 2023) me storing his old RQ6 Magic (Unfinished) here as their original location was lost – taken down now for a bit to clarify an issue. They are from times before AiG and can be outdated but there are 165 pages of the material.
