So, here is my system, the game uses the same system for spawning dragons, except, when you kill a certain number of generic (generic meaning named dragons like alduin wont count in this stat) dragons, there is a random chance they won't appear
Once you kill 15, 80% chance they will appear
30 dragons, 60% chance
45 dragons 40% chance
60 dragons 20% chance
this will gradulally decrease the # of dragons, so if you want, you can still kill them for dragon bones, but you get the feeling skyrim will be safer
Note: for dragons that are guarented to appear, say for radient quest where you have to kill a dragon for abounty or something, this mulitplyer will not apply
Your thoughts on this?
