Great video

- there is a massive portal community on Steam creating all sorts of tributes to the concept. Its almost becoming a religion like the star wars universe.

Played portal 1 and 2 from start to finish

i would have to say - easily the best video games i have ever experienced. And a brilliant sense of humour runs throughout.

Go check out Portal 1 on steam - its super cheap. and mind bendingly good fun.
And then lock in for months of fun in the awesome story world that is Portal 2.

Games can be a waste of time - but just like a good book - the state of the art examples are worth experiencing.
