Hey Chris & Obsidian,
Made an account here just to comment on this, because I am very interested.
Here's what I'd love to see, short and sweet:
Certainly a turn-based combat system, but one that isn't plodding. Take a look at the Grandia series, for instance. A setting that isn't strictly high/dark fantasy or generic science fiction. Something weird, self-aware and mature -- but not in a blood and guts sort of way.
Maybe it looks like this, on a really high level: A weird art style. A self-aware story. Mature characters -- ones that span all ages, sexes, world-views, etc.
Thanks and good luck!
