FOSS gamedev and creative worlds

This is a request for mod (directed to paramat more than anyone) that adds dozens of new biomes like in the popular minecraft
mod Biomes O' Plenty or Biomes+. I didn't put this in the requests section because they never get aknowledged properly. I hope paramat does thhis because he's the "Mapgen King".

Heh well the topic title certainly got my attention. I watch a lot of MC videos (Yogscast, Guude and BdoubleO, Vintage Beef and Pause Unpause, Sips and Sjin) and have seen lots of new biomes, quite often i get the feeling Mojang are watching MT and copying, because the same ideas seem to pop up at similar times.

I have seen proper swamps: mangrove trees actually IN water, with cross-shaped roots similar to what i was planning to use for swamp trees, also i have seen a second green coloured water similar to my swampwater, also craggy mountains with reddish strata in the rocks similar to my original paragen mod, also amplified biomes with higher mountains to make use of the 'huge' new vertical height of MC (256m :P).

What extra biomes are generally thought a good idea, in addition to the 8 of my paragen mods? Not promising anything i am busy and only work from my own obsession and inspiration.

LOL WTF biomes o' plenty has 87 new biomes!

This would be feasible once biome api(and mgv7) is implemented into stable minetest.

MGV7 will have mapgen flags for optional mountains and 'ridges', but the terrain will have a particular character everywhere, so one thing i could work on is not so much the biome and flora on top but custom terrain shapes like mesas etc. stuff that MGV7 cant do. My 'uniflat' mod is an example.

Slightly off-topic from biomes, I have a question/suggestion. (apologies for the disjointed post; it's late in the day here)

I like the MoonRealm concept, but I really want to have it in the default area (at and around the "natural" water line). Would it be fairly easy to replace (probably in LUA) the various naturally occuring nodes (dirt, sand, stone, most ores) with moonrealm-like nodes? Perhaps with moving the water line down (say, to y= -1000) and setting the mapgen noise settings so that things are mostly flat and largely single-biome. I think faking a vaccum or otherwise hostile air type would be the hard part (in addition to managing transitions from hostile-air to breathable-air).

You can disable the default mapgen by using MT's 'singlenode' map generator, edit the 'mg_name' line in minetest.conf to this:
mg_name = singlenode
... then start a new world, it will be empty, only air.
