My take on new random gen:
The biomes and their distribution is getting stale fast. I can't see how it's random anymore if you know it's "Desert south, snow north, forest middle.". I do like the idea of some bit of realism in terms of what biome borders another and having realistic "climate zones" of sorts, but why always the same layout? It's just washed out Navezgane minus a proper burnt forest and wasteland...
Burned forest only appearing in small dotted about patches doesn't work for me, that's essentially another proper biome gone from the pool now. In case of wasteland I'm somewhat okay with it, I guess. But not because I don't want a wasteland biome, just for optical reasons, as huge rolling hills of industrial rubble were always a bit weird. A new wasteland biome (with the resources and dangers of the original wasteland) could maybe be a mix of the rubble ground, and the old plains ground...?
Also not a huge fan of the bumpy terrain everywhere, but there's enough flat lands inbetween to compensate and find spots to build on.
What I DO like very much is the new road and town layouts. No road leading into nowhere so far and no seemingly pointless long gravel paths that just lead to a small campsite in the middle of nowhere. Different road sizes are cool, maybe the diagonal roads are a bit overdone, but those narrow streets in towns and the little rural "villages" (bundles of typical wilderness POI like cabins and such) are awesome. Only missing real highways now :] (and train tracks? Let me dream dammit!)
I'd love to see this combined with true cities (#bringbackhubcity!) that have the classic grid layout and there would be some real good variety.
