Not so much a game as a setting, I’d love to see World of Greyhawk get another fair shake as a campaign setting. Wizards of the Coast briefly and half-heartedly promoted it as a campaign world when it launched 3rd Edition. But it was quickly shunted aside for the more popular setting, Forgotten Realms.
Which is a shame, because Greyhawk was a world with a lot going on. It had a rich history, great epic villains, and a world rife with wrongs for adventurers to right. All the classic AD&D modules are set there. It’s where we get the creators of our favourite spells: Bigby, Tenser, Melf, Rary, Otto, Drawmij, Mordenkainen. Adding to the nostalgia factor, it was Gary Gygax’s home campaign. For that alone it deserves much better treatment than it’s received in recent years. Sadly, it seems stuck in limbo; WotC won’t do anything with it, but won’t let anyone else touch it either.
But maybe someday I’ll dust off my Greyhawk characters, and ride to adventure at the behest of the Circle of Eight. Or is that against the Circle of Eight? Whatever, either will be fine.
