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...

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
