I'd just carry on as normal really.I can actually live without games however the first couple of weeks would definately be hard if games didn't exist.My parents are quite strict about me being out late in the evening even know im nearly 17 :'( *sigh* which is why i normally play games in the evening but to fully answer your question i would just go on the computer more (Youtube ftw!!!), read more books and see my friends as much as possible,yes that means you Mike!!
so you better hope games dont stop.
