I am tempted (as a completely different topic of the previous 2 posts) to make the darklands even harder than they are now without the torches. I have come across 2 plugins recently that allow a fine grained list of additional factors that make stuff even harder. While I do not plan to make it so hard that it becomes impossible, I am not sure that the current darklands is really that much harder than the normal game, now that we have ender chests etc. The tow plugins are Monster Apocalypse and Extra Hard Mode.
If you are interested in this topic, please reply here with a comment and name the 1-3 most interesting features that you think would make the darklands more hard, but also more fun. We can then decide if we want to do that, and what we want to change.
As always, if we change something, we are always free to learn and improve it in case it becomes too hard or otherwise not as we want it. So please keep an open mind for this.
