I very much share the rave reviews the quality of this game that deserves its 5 stars. Unfortunately the new SHIFT forces the player to be constantly connected to the Internet and register by force GameCircle if not impossible to play! Icing on the cake to install it I was forced to uninstall it (using Titanium Backup I backed up the previous version and my backups). In short the policy of the App Shop this title is abject. I go back to the previous version that allows to play without connection.
