While many sites offer "repacks" (highly compressed versions of the game designed for faster downloads), keep these tips in mind to ensure a smooth setup:
Because the files are heavily compressed, the installation process can take anywhere from 30 minutes to a few hours depending on your CPU speed.
Repacks save bandwidth during the download, but they need significant space to "unpack." You’ll typically need about 50GB to 80GB of free disk space depending on included DLCs.
