It's the 9th of April at 4:37 pm in Australia now, and if this conversion chart is right it will be available to me at 7 pm.. so that's 2 hours and 23 minutes from now.
Lol, for me (in the UK) the maps come out at around 8.00, which is perfect for me because I always wake up at 7.00. =).
I already have them, but even if I didn't I wouldn't. Trst me, unless you've fiddled around with Google Sketchup's Sandbox componenets, you're going to have no idea what to make. Orbital and Assembly are fun though. Just a hint: all the skulls are out of playable sight and reach, but the one on Assembly is really easy to find; I found it myself.
