How does RuneQuest: Adventures in Glorantha compare to 13th Age in Glorantha?

The brief answer is... you don't fully know yet because neither book is complete. However, we're likely to cover most bases (character creation, cults, magic, monsters) to a similar degree albeit from very different perspectives that fit the nature of the respective game systems. 13th Age in Glorantha will obviously have a heavier emphasis on the Icons whereas RuneQuest: Adventures in Glorantha will be more 'down in the dust' which fits with the overall ethos of RQ Glorantha gaming. However RuneQuest: Adventures in Glorantha will include HeroQuesting and also how to emulate HQ-style magic using RQ6's various magic systems.

Both books will also be quite awesome. Buy both.
