"The first and most important issue I would like to address is
that no, you do NOT require internet access to install or to play
the games, you do not need a disc in your drive, and you do not
need to enter in your key or password every time you play. These
are all myths. You need to enter a key and password (and optionally
your email address) when you install the game, and that is it. You
do not need to worry about it again.
"Our system uses a policy of 'Innocent until proven guilty'
which means that you can ALWAYS play your game, unless the system
knows for a fact that there is a reason you shouldn't. This is the
opposite to most DRM systems, which assume you do not have the
right to, unless you prove you can."
