Microsoft has the semi-right idea with letting people use the XNA stuff to create games for the 360. Sure it is pretty locked down, but it is still is doable and well documented. The real hard part is that coming up with the idea for a 360 game is HARD, not to mention people expect "next-gen" graphics and sound for 360 games which is almost impossible without a large team. On the other hand, anyone who picks up a Wii controller immediately can come up with 10-50 ideas along the line of a Wii Sports or other mini games. And I think people are just fine with the quality of the graphics of the Wii. Throw in a standard "Mii" library for creating the characters and you are rolling right along.

Too bad I don't think Nintendo has their system set up for this. Oh well.

Check out Aaron Margosis' blog at http://blogs.msdn.com/aaron_margosis - he's got some very interesting helpful bits for folks who want to start down the path of least-privilege access on Windows. It's not the "official" word, and it's not at all comprehensive, but it's part of a wave of folks inside MS who are putting these practices to good use right now.
