Gateway: I Have No Idea

I've been getting the same question quite a bit from people lately (myself included), and that question is "What are you going to run at Gateway?"

I have no idea.

Whatever it is, it'll be something FATE-based, of course. I just don't know what it'll be. Nothing's really jumping out at me right now in terms of genre, and I don't have some wacky/high-concept idea (like "Paranoia + Star Wars!" or "All the PCs are gibbons!") that's grabbing me, either. So... I have no idea.

Anyone have any suggestions?
