Really looking forward to this, as I may finally get my group to move away from d&d/pathfinder/5e systems to something different, yet which hits the same themes.
With Runequest 6 the approach is very much a tool box that gives you a lot of options to fine tune the rules to your settings, but on the con side it leads to a "lot" of work before play. Here I am thinking of fighting styles, weapon groups, cults and what spells they have access to. I know that setting books remedy this and do the work for you but what about Classic Fantasy? Will it take the same approach or will there be defined examples of these things? Or maybe a seperate settings book for a Classic Fantasy line?
Also, will the basis of it be older D&D versions, like the BRP Classic Fantasy, with things like Clerics using blunt weapons, Alignment restrictions on certain classes and so on. Or newer versions that removed some of these restrictions? While I know its down to each GM to change as they want, then I am just curious about which inspiration you are drawing from.
