The map this rev was a bit plain - sure, it was flat land everywhere but there was an absence of large hills. I like previous revisions' mix of naturally generated terrain and WorldPainter.
Mesa biomes are fine, but they were too big in rev 28 - that's probably where all the hubbub came from. Custom stuff is great, I like seeing large redwood trees and the like.
I don't really use Classic Creative, but I don't understand the switch from space to regular spawn in the middle of the rev.
Speaking of spawn, spawn should give immediate access to spawn city/randloc. Perhaps make it like P by creating a maze of rules then a doorway to spawn city/randloc sign.
Cardinal roads should exist for accessibility and guidance purposes, but maybe the freeway themes don't float everyone's boat. I personally love them, but other people with themed builds might not think so.
Speed build should continue as usual.
