I am very excited for this: Hades was such a masterpiece of game craftsmanship that even if Hades II doesn't quite hit the mark it'll still be enjoyable.
The protagonist this time is apparently Melinoë (https://en.wikipedia.org/wiki/Melino%C3%AB), and it looks like Hecate is going to play a major role from the trailer. (These games make me wish I knew
more about obscure Greek mythos lore, which is another thing I count in their favour).
