What a fun game! I can't pin any specific genre to it because it's a mix of many things. It's about a town full of Vampires so I suppose that may draw some and deter others from playing. You begin by picking either male or female and then choosing from many different faces and hair colors. The game kind of feels like a simulation in the fact that you have to work at a job to earn money for everything. (By the end of the game, there are a ton of jobs to choose from). You have to rest and/or eat to regain your strength. You also have to visit schools and learn new things to raise your stats in an RPGish sort of way. Then there's my favorite part which is dressing your Vampire up and decorating the interior of where they live. Buying better clothing will raise certain stats. Buying better furniture, knick-knacks, and pets helps your Vampire to relax more so they gain more health and mana when resting at home. You also help out a multitude of Vampires in Twilight City with different tasks. Some of said tasks involve hidden object scenes so you can add HOG into the mix. You can cast spells by buying them, learning them, and then drawing their symbol on your spell sheet. You ride a steed around town and can buy better ones that move faster and even heal you while you're traveling from building to building. And when I say steeds and pets, don't expect a lot of them to be normal. Vampires like undead and demony things.
In short, this was a pure pleasure to play and I definitely plan on going through it again.
