We promote a grief-free environment were you can pick your own game mode and where you are free to build anything anywhere. We have a limitted number of mods (except of course for the tekkit mods), the only ones we have are for anti griefing. We do this in hope that you can concentrate on bulding and not on whether you are building in the wrong spot.
We are soon to be adding a dedicated server with 16 gigs of ram and 8 tera bytes of hard drive storage. That means that we will be able to have up to 100 players at once!
