I don't know about all of you but i would love to have something like the creation kit on the Xbox 360. Who is with me?

Everyone.

It's often requested, however the XBox 360 likely lacks the hardware and software to run it, and even if these weren't hurdles MS would likely block it (it appears they've blocked user-made mods).

Unfortunately this topic tends to attract a lot of problems so I'm locking this. However if you're interested in editors like this on the XBox I'd suggest voicing your opinion to MS - I don't know the likelihood of this happening with the current system, but perhaps the next one will allow for more user-created content?
