The new snapshot just came out! 13w36a
So whats it all about? - In a short description, its world generation, decoration, nature and the water and its creatures.
What about the new world generation? - Now we have a large amount of new biomes, a large amount of flowers and grass, new biomes like Savannas, Mega taiga biomes, Ice Mountains even a Flower Biome and lots of more. So much detail to the world.
Also, a lot has been added to the options menu, with the secret settings also, i'm guessing ,theres a way to access it , but first you have to achieve something. A whole new section of settings just to sound. Also new rendering techniques. Theres is also a /summon command, that allows you to spawn any entity wherever you want to and when you want to. And the new /achievement command, that allows you to give an achievement to anyone. So map makers, GO CRAZY! Tons of stuff, i can only imagine how horror maps will be made , with the ability to spawn a mob right in front of your eyes. New fishes with a poisonous one aswell. Two new enchantments for the fishing rod.
You also get this cool effect whenever you fall on a block somewhere high.
New amplified terrain generation, amazing! I think there also now floating island biomes as seen in this picture:


New dirt block. Podzol. I assume that the poisonous fish is ment for brewing. You can initiate running by simply pressing CTRL now! More rebindable keys. And hotkeys. The roofed forest biome is looking fantastic. Villages seem to spawn in random places, even on top of mountains.

But overall is this snapshot good or bad?

Well i don't seem to have any problem with it currently, theres a lot of more exploration to the game. The food is not generated too often as some people might think. Its actualy even more balanced now. Gameplay of adventure maps can now be upgraded with the /summon command aswell as all the decorational. The game looks a lot more beautiful now. I would say that this is indeed a great addition, some people might find some things annoying, like having to reset your maps to have new generating. But the update is really good, balanced nothing has gone wrong and its only to increase the gameplay and the asthetics. This snapshot has a lot to it, also with the hidden feature we don't know about yet. My opinion: This is one of the best snapshots we currently have had, or maybe even the best.

So what are your thoughts, what do you like and dislike?
