Shrinkwrap contracts have repeatedly been found to have no legal weight in
the UK. I therefore won't bother commenting on the contract. :-)
However, in the UK you should include a notice like the following:
<Your name> asserts the right to be indentified as the author of this
work, in accordance with the Copyright, Designs and Patents Act 1988.
This gives you the so-called 'moral right of paternity' -- i.e. people who
quote bits of your game have to identify you as the author.
