When Cloud Imperium Games will ship the fully patched final game, the Star Citizen download will likely be around 100 GB. That has been confirmed by Jeremy Masker, Game Operations Director with the developer. "The game compression and asset removal is unlikely to yield such high gains that we will be able to reduce our client size to 30-40gb. The size and number of assets that are left to deliver means that our client size is much more likely to be 100gb", Masker wrote on the official forums.
