No. When TSR was bought all of the settings went to Wizards.Is there a possibility that Gygax family still owns the "Greyhawk" IP in some way?
One, the Adam West Batman was the best Batman. That’s just obvious.Bob: Yo, Frozen North. I'd like you to watch this TV Show.
Frozen North: Okay, what is it like?
Bob: Well, it's kind of like that show you like... Batman. Except instead of being an Adam West "camp" take on Batman, it's actually a gritty take on Batman.
Frozen North: Okay! So it's exactly like every Batman. It's a campy Batman. Got it!
To move away from the oft-productive topic of food metaphors for a second, let me ask some questions:
1) What specific elements of Greyhawk would need to be maintained to capture the idea of being "respectful to tradition"?
2) What elements of 5e could be introduced into Greyhawk in a way that respects the Greyhawk tradition? What elements would specifically need to be excluded?
3) What novel concepts could be added to Greyhawk that both enhance the Greyhawk flavor and add to the 5e experience?
One, the Adam West Batman was the best Batman. That’s just obvious.
Secondly, doesn’t this just prove my point? Aren’t the “revivalists” like fans of West’s Batman, seeking a Batman remake that is more faithful to the West version, despite the fact that many interesting settings have come out in the interim and that its heyday was 40 years ago?
I love West’s Batman. I don’t think it needs a revival.
I kind of hate to come up with this point, and maybe someone can destroy my logic here. But rather than comparing Greyhawk with Conan and S&S, wouldn't a better comparison be Game of Thrones with more fantasy (races and monsters) and slightly more magic (Classes and items) ?
While not perfect, I think it is close and could be used to show what Greyhawk offers to younger players who are not overly familiar with Greyhawk, the world of Conan, or S&S in general. I should have quoted the poster who talked about the Tension of Greyhawk.
