When I purchase Simcity 4 , can I play without Internet connection ?

[nsfuid]

      I have a couple of questions .

   Question 1: Do I need to have a monthly service to play Simcity 4 Digital DL if I purchase it here ?

      I have a new computer and of course my previously purchased  ( Many years ago ) Box set with CD's no longer work with modern windows PC's

   Question 2 : Will the Simcity 4 game I purchase here be fully patched for US residents ?.

       Thanks in advance .
