This is a really hard question for me and I've listed some of my top choices. I have a lot more, but have really tried to narrow it down to just the really favorite ones. They're packed in groups which go together in either genre, game type or something else along those lines (I didn't really pay much attention to the categorization, actually). I've just jotted these down from the top of my head, so there are definitely more options I could put down.
So, in retrospect, I like a lot of things. A lot of variety in there by the looks of it. If anyone wants to know more, or what specific atmospheres I enjoy the most, hit me up in private because I tend to talk a lot about the emotional bond I have with various game settings. In short, I mostly prefer and enjoy a lot of story-driven experiences with good character development in a lot of forms.
