In the chests, I hope you provide like a bow and some arrows, and some wooden tools
I don't see why tools are needed since you can't really build or mine or destroy anything.
Also, just an idea I came up with, most of the reason why getting rid of the whole building concept of HG servers in minecraft is because of the easiness of it. You can cut down two trees and have a decent, spacey house. But what if you got one of those "increased difficulty" mods that makes blocks harder to destroy and stuff. I found that it is pretty hard to cut down trees when your tools are weaker and your hunger rises at a higher rate. I would, however, keep the "no mining" rule as mining can give people very large advantages over others, and with no mining you can limit people to wooden tools and the such. It would also be nice if there was a mod that made it so players can't use their bare hands to destroy strong block such as wood and dirt, but easier ones such as sand and wool.
I don't really have the links to any of these currently as I haven't used any mods since forever, but if your interested I could look for some.
