This "wolves roaming the countryside" issue seems very interesting to me. Everyone is either complaining that there are way too many wolves or that they've never seen a wolf in their game.
Well I'll be the first one to say that I've seen both situations in the multiple games I've played. In one game I suffered from the wolves being everywhere and the couple of games after that I had a better variety of animals including bears, elephants, lions and a spider or two.
In support of the new animal spawning scripts, it seems to me that every game is different. I can usually rely on bears or wolves being around to help with my city culture ratings or conquest of low level enemies but there seems to be no guarantee of what the animal types will be or even if they will be there in sufficient numbers.
However, there are three things that I've noticed that I think are concerns:
1/ The wolves seem to reproduce much more than the other animals if they are left to their own devices. Even in games without many tiles for wolves to roam, the wolves(if they are there and left alone) seem to have greater numbers than the other animals (eg I don't recall bears in stacks of 3 or more in any of my games) (It seems that Anaztazioch may have something to say about this though since he had a throng of bears at his doorstep )
2/ With the other animals I usually can't find enough of them to fill all of my city's carnivals. With wolves (when they are there) there are so many that I usually have to disband them after I capture them.
3/ Its annoying to have to wait every turn for 8-10 wolf battles whenever I move my hunter to neutral lands. Thats really the biggest thing for me. When the wolves fill the map it is
NO FUN! It is almost like the Grind in an MMORPG.
Maybe the team could change the wolves spawn script so that wolves don't spawn like the plague if they are given space to do so. (I know that this was done already but it still seems to be a problem).
