I'm not sure what sort of rapid shifts you're expecting to see in biomes. I think that shifting too frequently would look pretty odd. And you're saying that in all your scouting you found not a single resource or natural wonder?
There are some.... er.... I think.... but they do seem very, very sparse. Even after letting the scouting happen for quite awhile, there really wasnt many of them; most of the map remains featureless (not counting other cities that is).
Looking at the save though I started near two wonders (as in, both were inside of my city boundaries from the start, because RNG!) but other than that I havent seen any. And of course there's the occaisional tile that has some sort of resource on them, provided that the Skylaxians arent currently sucking those up. There's the occaisional couple of "rocky ground" tiles or mountains, but that's about it. And water of course.
In all honesty, I think this is still going to be a problem with the presentation; the landscape itself just isnt very interesting visually. And you know how people are about that, it's all about teh grafx after all
It's just very... featureless, particularly early on, but even when zoomed out it still feels that way. Now, once some stuff is happening, and you've got some buildings up, and there's other cities to view and stuff as well, it looks much better, but yeah, the landscape itself still just looks very stark to me and I find it hard to care much about most of it, and early on, it's all you see.
At least for now anyway... these are still early impressions from this new version. Which I will indeed be starting over when I fire it up later due to the jungle problem and some of the confusion.
