Planet Minecraft

Yes I've changed the post again!

I'm hoping to make another mod in Minecraft for 1.4. I want the mod to make survival more fun and challenging. The mod will add lot's of mobs, blocks, biomes and items. There won't be a dimension in this mod because DimensionAPI often takes a long time to update. Here's an example of I want the mod to do:
-You have to kill a new mob to get a special item
which is used to make a special block which gives you a special achievement.

However, my brain isn't very good when it comes to thinking up good, creative ideas so I want yours. You can suggest what the mod should be, what it will be based around, mobs, blocks, items and biomes in the mod, goals in the mod, ores and armors, and more.

Please leave your suggestions below

Thanks,

Space, the final frontier! maybe a portal out of redstone lamps and if u activate em all, it opens o.O in the actual space there could be planets and some sort of anti-gravity maybe? pre-generated space ships with plasma blocks that if u break, u get plasma ingots which can be used to make plasma tools. If you activate the plasma block with redstone, it will fire a plasma bolt in all directions, killing 1 mob, or destroying 1 block?
can only be stopped from firing in a direction by putting iron block in its path.
maybe also aliens everywhere? these are just what i came up with when i was bored in algebra XD

There's already a plasma mod out there but I like the idea of the space dimension

The Wither

if the nether is hell, you can make heaven
So you're in the middle of the sky, sitting on cloud blocks, with floating islands and temples here and there

There IS a heaven mod, noob. It's called the Aether, heard of it?

Make A Sort Of Spider Hive One? With Spider Webs And Stuffs...Not Much Time To Go Into Detail, So Just A Small Suggestion...

If Not You Could Do A Giant World, Where Trees And Things Are Larger, And There Would Be Giants In Castles And Stuff,the scale for blocks would basically be something like 2x2x2 or if you wanted to make it pretty large 4x4x4

I like your ideas so far but I'm thinking of making an Iron Golem dimension out of Iron Blocks. Any suggestions?

make a diamond world where the portal is with diamond blocks and the tree are made out of diamond block and dirt is diamond ore but so many mad mobs

I think the iron golem dimension should have like Iron ore deposites everywhere but instead of irone ore giving you the block its a special Iron Ore that gives you an Iron Ingot and then new rare blocks deep underground that give you actual Iron Tools/Armour they would have to be about as rare as diamond but I think it would be Epic

I updated the post to include Mobs.

A zombie dimension
Destroyed castle and at the end a big giant zombie boss. And also zombie warriors with strong armour and epic swords
