I had a real blast with those levels. But they could have definitely been better even on LBP1. I am so pissed I never published my first Veldin level. It was virtually identical to the one I made in LBP2, with a few less decorations, accurate materials, and no Sackbot. But Novalis was the really incredible level. Even though it wasn't done, I managed to make the first 2 paths loop around quite nicely, and even captured the proper feels of the different areas of the levels… I really did push the layer glitch to it's limits too.
After living away from the city our whole life I'd always wondered what it would be like living in the city. A couple of years there tells me that unless you have alarms everywhere your house will get robbed, and overall living conditions suck.
I'm glad I don't have to put up with that anymore.
