Edit: I'm now using this thread to keep an occasional diary of my antics on the server.
This is discussed in the sticky, but since the sticky is 35 pages long and the server has only just been reset / restarted I imagine few 'new' people will bother reading it to realise that, hence a new thread to signpost it. (http://www.failheap-challenge.com/sh...))))-MEINKRAFT)
Dynamic (live!) Map:
Vanilla Minecraft with "Factions" Mod. Factions mod allows a faction to claim chunks of territory in which only they can build/destroy blocks and they get a HP advantage.
Killing players in a faction, or them being inactive, reduces (temporarily) their ability to hold territory allowing you to fully "attack" someones territory if you dedicate yourself to it, but its not easy.
Creeper dmg and explosions are disabled inside claimed territory (but can damage claimed territory if they explode just outside).
Basically its like normal SMP minecraft, but you can protect your buildings / items fairly effectively, but on the flip side people are allowed to try and attack them and you. this makes it a lot more fun as you have to build defences, moats etc.
Come join - Ask me nicely ingame and I'll give you some shit to get started (some iron tools and some torches at least).
