I said yes because of a couple reasons, namely that I've already ordered it because my girlfriend is excited for it, and because I will find the extra subclasses and mythic boons useful for extrapolating to my other games.
I care frankly nothing for the setting itself and aside from Hades and the all of the mythos surrounding him I have never enjoyed greek/Roman mythology, mostly stemming from not liking the blantent racism of ancient Greco Roman culture (which was albeit common for anyone back then) and finding the greek/roman gods largely unlikable (special shout out here to Apollo, biggest ***hole of practically any mythos) because they had no accountability and were largely worshipped only out of fear. It makes sense given their climate and function of religion in their society, but it doesn't mean I am overly fond of it from an upbringing with it, or blinded by nostalgia. I'm also just not a MTG fan either.
Norse and all of the eastern mythologies were always more my thing.
