Stone Henge was a much more awesome name.
I remember the cool ideas I had about making it where you could gather materials to create different kinds of free-standing structures like catapults, guard towers, bone fences, and huts. (Which served as instanced spawn points.) The ideas I had for rides (mounts) were pretty cool too. Mastodons that sprayed jets of water, fast-moving raptors with claw and bite attacks, slate rock tanks that shot bursts of fiery volcanic rock, etc. Great material for a PvP-heavy server of this genre. Don't know if that's what you're shooting for, but I figured I'd put it out there.
