While those are nice, it seems there could be a whole lot more to it. Perhaps some of what I'm saying has been suggested before, but not any time recently, and I felt like making a new thread

It would be nice if doing missions had an effect on the game world. I'll take killing carnivores for instance. I know around Yrkanis, everyone and their brother kills dogs for fame. You'd think with a lot of people doing that, the gingo and ragus population would decline. And it should! On the other hand, if no one was doing those missions, the population should increase, and make it more dangerous in the area. A lot of newbies have trouble leaving Yrk because 10 feet down the road you're being swarmed, but doing the missions should help that.
(actually it already does, the dogs are killed so frequently it's actually been numerous occasions I've walked through there with not a dog anywhere, because they're being killed faster then they spawn, but that's a diffrerent situation altogether...)
Also, there are the kill bandit missions. If these missions are left unchecked, the bandit camps could grow in size, making them more of a threat. It would even be nice if if it was allowed to grow too big, they'd send out small scout parties to attack and pillage any homin they came across. But if the missions are completed in earnest, the camp size dwindles.
There are missions that ask you to collect food for friendly tribes. If that isn't done, the tribe population dwindles, pretty simple. And they're less likely to be able to kill aggro on you if you run there for help. But if they are provided with food, the tribe size increases and they can kill things you drag there even faster. (could also counterract your opposing religious faction, if they like to kill that tribe for fame. Build up their defenses insanely and watch some player have a big surprise)
For all of these, it would be necessary to have minumums and maximums so regions weren't totally devoid of a mob or tribe or overflowing with them either. Also, it's probably true that low level zones will have the missions done much more frequently, so the changes there would need to be more gradual. Zones which are mostly player empty though could have large effects from just doing the mission once, if a team is brave enough to go out there and face the dangers.
Besides, if players knew killing carnivore missions would decrease the population in their favorite harvesting area, they'd be more likely to do it.
There are also other mission types which I haven't thought of gameworld effect of yet:
-Craft equipment for the tribe (make the guards stronger? or maybe just adjust their population some more)
-Harvest random items to the tribe: dry straw, flower petals, firefly abdomen? I don't even remember what all that is for.

Also, there should be slightly different effects from doing missions directly for Kami and Karavan. But I'm not sure what, hehe.
What ideas do you have to offer to fill in the holes?
