Since NFC has Beta 1.3-Beta 1.7.3 generation, there are some good seeds out there to find, and we might discover new ones ourselves playing NFC that are unique to NFC since structures/ores/other subtle things are different.
I will be looking here (and other sites' archives for beta seeds XP) for a new and cool server seed. You guys can go ahead and post seeds here and link to where you found them, it doesn't have to be new.
Does "Archespore" have many cool features or just that one for spawn(?)? Perhaps we could really discuss types of worlds we want. Do we want relatively mountainous worlds, relatively flat worlds, deserty, snowy, hilly perhaps even? I know seeds that cover some of the above. (To memory. I haven't seen some of these since 1.7.3 and earlier) I say we consult the community on this.
