The first XNA Community Games have appeared on Xbox Live. You can only see it if you're part of the NXE beta, but this is a big day for the indie community IMO (and not just because I'm an MS XNA MVP but because I'm an indie
). You can see a screenshot of the games here
There's at least one more game that's been approved and should hit within a day or so. By the time the NXE rolls out on the 19th I imagine there will be at least a dozen or so games available. I've got at least 2 or 3 game ideas that I'll be working on as soon as I'm finished my 2nd XNA book.
If you're interested, more info can be found on the XNA Creators Club site
You didn't really think I was going to not talk about this, right?
