I did most of the game script for FFX-3 (LNA) if you want to check out my writing (fanfics aside). I tend to favor conflicted flawed characters who are trying to rebuild their lives after severe trauma, usually through interpersonal relationships. I like characters that form makeshift families (even my villains).

I think of my tone as dark heading to light. Some examples:

My perennial favorite is a general who adopts a daughter from a country he conquors. He later befriends a ambassador from the same country who becomes like a mother to his daughter. They share a mutual attraction but are too bound by honor and duty to do anything about it. The villain appears as a necromancer who tries to precipitate a war between the countries. The twist is she claims to be the daughter's long lost mother. I've actually tried to make this using two different versions of RPG Maker.

Another one I've been working on is a demon that possesses a human and recruits all his old lackeys. The thing is, the human host softens the demon's heart so he begins to treat his followers with compassion for the first time. Naturally he also inheirits all his old enemies, including some who are good but self-righteous, and others who are even more twisted than he is. I wanted to make a Flash RPG with this one, but I may just try it as a dating sim (which is much easier to program).

EDIT: I also like designing world maps.
