Oh when did you download it?
The Mod patch for 2.0 was 40MB.
This is the Full Version. No patching or updating needed anymore its 1,44 GB cause it includes ISO file in it. It is a all in one MCG play package containing original, all user campaign missions and multi-player feature for gameranger. Completely overworked.
Edit: Somehow links got misplaced. Corrected all links it is DEFINITELY 1,44GB folder now.
