The best way to describe Stray Gods is Glee meets murder mystery meets Greek gods, presented with a comic book art style. This is a narrative adventure game, letting you define Grace's character with your choices. Some dialogue options are only available if, say, you choose to make Grace charming, while others are only available if you give her a rough, punk-rock personality.
As Grace, you work with various Greek gods to figure out who murdered Calliope, while breaking out into a musical number here and there. Oh, and if you don't solve the murder within a week, Grace will be killed by the gods. Unless you're a musical theater hater (no shade if you are), this is absolutely a narrative you'll want to know the end of — and probably replay again to give Grace different traits.
