There is nothing to trust in here.

Repackers don’t crack games. It’s someone else, usually scene. Once the cracked game is available widely, repackers just do whatever they do, which is very questionable as there is constant flow od reports with problems.

So the original question stands. What’s the point of using repacks? To save 10GB on download, then to deal with unpacking for ours? How many countries still have a download limited Internet connections?

Genuine question.

Why anyone even bothers with repacks?

Just to save few gigabytes when downloading, only then to waste a lot of time messing with it or just installing as it takes forever
