Dude, what the heck?
I am interested in learning about the Witcher. It is a series I mean to get into, but I haven't found the books yet to read it. And, considering I haven't finished a video game in almost seven years, I don't want to go and buy a game I'm not going to finish... again.
There have been cases made about Greyhaw being grounded. Other people (not me) have said that is false. That between Iuz, Cuthbert, Vecna, Zagyg, and the enormous plethora of artifacts that Greyhawk is fairly gonzo in a lot of ways.
Yeah, Greyhawk has always leaned pretty hard on the Weird. Erol Otus artwork. Six gun toting wizards. All sorts of dimensional portals. Yeah, GH is pretty gonzo.
Darker themes? The only "dark theme" people have mentioned is that their PCs are greedy. I literally haven't seen mention of anything else, except a module about slavery.
Ah, now here we have a bit more meat to work with. The Slaver series was pretty seminal in the development of D&D. Certainly as well known as the GDQ series. In addition, you had things like Cult of the Reptile God where a naga had set itself up as a god in a small town and converted most of the town into cultists. It's a VERY dark module. Again, too, looking at the setting, there are very few beacons of good. Evil is VERY powerful in GH. We're not talking some far away land, but, the main countries of the setting are outright evil. Playing that up would be a good hook for the setting.
Look. I am fine being convinced. But I'm not going to be a bobblehead who is just going to lie to you and yes man my way into you people not dumping on me.
The idea of a world where most of the people in it are of dying races? That is interesting. The idea of a conceit where this is the setting for war and nation building, where PCs can climb to challenge the current players of "The Great Game"? That is compelling, and would open the road for a rule set people want.
Honestly? I think this is EXACTLY the direction that should be taken.
But you can't sell a setting on "I'm a mercenary who fights for gold" because Modules and Adventure Paths aren't a setting. I don't care if there are literally hundreds of modules and adventure paths for FR that are about saving the world. If I am running the setting, but not an AP, then I can do whatever I want.
Thing is, GH is based and developed mostly through the modules. You simply don't have the background material for GH that FR does.
