I'm looking for two altered world generators. I would like one that creates an overworld with sea level at 80, and potential sea bottoms of 5-10. A nice dispersal of vast oceans (think dozens of chunks across) along with land-masses of various sizes with the normal lake and cavern dispersal. Nothing that spawns below lvl 33 would spawn on this world, and there would be no bedrock. The second would be underground from base to top, with gold starting to spawn at about 118, but with less frequency than is typical for 32. This would gradually increase to normal rates at about 60 for gold, 30 for Redstone and run to bedrock. If anyone could do this, that would be amazin'.' Addendum: A third one is actually needed. Normal spawns in the Skylands and a normal day/night cycle.
Look at this world gen, Its got underwater cities, vast oceans, and awesome islands. The guy who made it left a surprise at the bottom of the caverns to: http://overmindgames.wordpress.com/2011/06/12/deep-blue-minecraft-map-generator/ I think it works for SMP worlds too.
