I'd guess the most popular genres (or maybe sub-genres would be more appropriate in the game context) generally might be crime, horror, mystery, and the ever-popular harem scenario in all its diverse forms. Many projects are some combination of those four, and I'm sure some don't fit into any of those categories. I've played and enjoyed maybe 25 or 30 of these kinds of games, which is a very small percentage of the total output available, but I have to say my favorites are the harem games, usually with some mystery, crime, or sci fi elements in the mix. I admit that I like the ones that have you grow a business/financial empire of some kind, too, even though they typically involve a lot of grind. I'm curious, though, about how my tastes compare with yours. What are your favorite game story genres?
