Ok.
As I stated before I played runequest before -the French version from Oriflamme, I never read it so I don't know but the game felt a lot more like heroic fantasy with d100 rules. The world I find in the RP in Gloratha is soo much different! very dense, deep and mythological. I usually eat a 400 page rpg in a day or two but this one is like this fantastic cheese cake so tasty but hits the bottom of your stomach like a brick. I find that I need to take it slowly and in small bites, going back in forth with some browsing on various wiki to read the names.
I noticed the use of capital letter for some common words that are used in a mythic way. time and Time are used in a very specific way. There is the regular time, Time and God Time and since French is my native language there are place were its a bit confusing. So I need to read some part and look at the context were it is used, look up on a wiki and I realized that the background part of the book have to be read like a philosophical text - slowly with intent. You cant just read - you have to dive and immerse yourself and and it burns my energy much faster.
It is fascinating and very rewarding but require a lot more attention and focus that the usual book. I can see why many people might find this very daunting.
Also you get a fluff part, then a crunchy chapter, then another fluff chapter then back with rules and systems ... most rpg pack their rule in one half and the background and worldbuilding in the other.
its odd but I like it. It might (will probably) make thing a bit harder in actual play when you must do some page flipping judo to find something on the fly when you play but its does help the first read I think.
anyway, I just got through the combat chapter (phalanx combat wow really cool) and into the magic we go!
