It went on sale here in Australia at midnight last night (at the same time as the XBox360 launch here... heh, it really
was a launch title for the 360, here).
I didn't get mine until 9:30 this morning, in fact, because I'd pre-ordered it. It was in this morning's post, though, so that was good. What wasn't good was that I'd recieved it at work, so I had to
have it but not
play it until lunchtime (although I set it installing on my laptop while I did other stuff, so I could jump straight in when the time came.)
I liked the fact that it detected my hardware's capabilities and scaled the graphics options down automatically. I was a bit worried about my laptop's ability to run it, since one of the more intensive Morrowind mods (Wizard's Island) brought it to its knees, but the framerate has been (mostly) fine, and even with the graphics options down low (where it set them) it looks plenty pretty to me

What with stopping part-way through and going back to the start to play through again with headphones on once I lost the audience, I only just got outside before I had to stop, but it's been great so far!
