This is obviously just my opinion, but I think we really need more creatures spawned.
Don't get me wrong, I'm in full support of keeping the theme (no creepers, no zombies, etc). but what we have isn't really "survival" gameplay. Maybe thats not the goal of this server? It seems if I walk for 5 minutes, I might see 1-2 skeletons. I want to be in more danger! Specifically at night time.
I'd like to see a lot more skeletons spawn if possible (since they are meant to represent indians). It'd be great if we could get a texture skin for them also.
Also, what happened to the hostile wolf idea? I thought that was really clever and sticks to the Goldrush theme.
