A sequel would be great. It could retain the excellent choice and consequence of the first game while expanding and improving upon the weaker gameplay mechanics. Unfortunately, the game sold like crap and Sega (which is currently facing financial problems) owns the IP. Still, I'm surprised there haven't been any high-profile spy RPGs yet. In fact, there are tons of unexplored settings for RPGs yet 95% of the RPGs made still use generic fantasy.
