I find it amazing that Minecraft suits so many passions...

If you like drawing (you deram of beeing an Artist), you can work a pixel-art picture.
If you like building (you are interested in Civil engineering)... well no coment. Build cities build whatever.
If you like trains (related to the last one) go ahead and do a railroad, just as you want...
If you like adventure (you just enjoy Role-games and playing), fuck there's a whole lot.
If you like maths/elecrics (you want to be come a computer scientist or mathematician or you're interested in electronic engineering) you can play with redstone and build such incredible shit nobody will belive.
If you like music (and you dream of beeing a musician), you can do songs with redstone and musicboxes...

fuck, how is this game so awesome?
