You will not need Xbox Live to play Grand Theft Auto Episodes For Liberty City if you have it on disc. You will only need Xbox Live if you wanted to download it off of the Xbox.
You can download some Grand Theft Auto games for free. Search on google for demo downloads or get a Bittorrent client or Vuze and download the games as torrents.
