Been playing this alot lately really a very great game considering its still in alpha, anyone else play? what are your server deets if your playing multiplayer, The server I used to play on has been taken down for awhile while the guy that ran it moves house so im looking for somewhere new to play

I mass don't understand this game, what do you actually do?

Yeah I've only played the single player with monsters and I can't seem to see the point besides simply surviving? I usually survive the first night then travel too low in a cave and get killed by angry creatures.

Build and mine stuff, Its basicly like playing with lego.
Really you can play the game in many different ways depending on what you want to do and what you think is fun.

If you only want to build amazing structures, you can play on creative mode where you have unlimited blocks and no need for tools
and build things like this... http://www.youtube.com/watch?v=kn2-d5a3r94

If you want to just explore the world each Procedurally generated world has a theoretical surface limit 8 times that of the earth, so there is alot of world to explore.

(The second video is using a custom texture pack)

If you want to play it as an adventure game killing monsters and searching for treasure there are a few custom made maps ideal for that.
'Skylands for minecraft' being the best one I have seen though i couldn't find a decent video demonstrating it

Playing survival single player mode can be a surprisingly spooky experience, trying to dig out treasure to build with, while avoiding zombies and all the other creepy crawlies that lurk in the dark, the music and sound effects are great. though unless you have something in mind that you want to do / build, you can really run out of interesting things to do fairly quickly
(there are so many tutorial videos etc that I couldn't be bothered sorting through them to bring you the best, just search 'minecraft the nether' if you want to see the hell world though that you get to by going through a slip gate though)
http://www.youtube.com/watch?v=0VWnQHS-ffs is a brief tutorial on how to get started with survival single player

But really the best part of minecraft I think is the survival multi-player, where you play on a server with your friends working together or separately to build the most awesome things you can think of,
This is an old map of the server I was previously playing on, to that maps scale a player is about the height of two pixels and has a 1 pixel base

sorry for the double post, but just found this map of a server where they have done some fairly crazy stuff
