So as far as story and characters go, I think I have just about enough to work with to start up a concept development thread. I still need to define a clear antagonist, though, and I also need to get a more concrete idea of what kind of gameplay would suit this project best.
Seeing as the game revolves around three parties of two characters, it's obvious that whatever gameplay style I decide on needs to have a strong reliance on synergy between party members. In the beginning of the game, the main duo, Gwen and Ulrich, have only just been paired together by the organization both serve under. It's not accurate to say either of the two are "green," but both have a long way to go before mastering their respective arts and, more importantly, neither of them have any experience working together. I want the player to not only see Gwen and Ulrich grow stronger as individuals, but to realize on their own how the pair's abilities come to compliment each other.
