Why does the launcher need 4+ GB of free space?
The 4 GB is a rough guess. The launcher tells me to free up disk space when I have 3.5 GB available, and it doesnt complain with 4.2 GB available.

Its not downloading anything, so why is this?Hello Mani

The game may not be downloading anything, however it is unpacking data from archive files continuously when playing, and creating temporary files and so on. This means that in addition to the amount of space it requires just to have the game installed, you may need extra space for operation of the software.
