Most of dodi and fitgirls repacks are actually just other peoples releases, they aren’t installing any cracks, that’s why the upload notes always say “based on codex”, or elamigos, or empress, etc. Unless what you meant was that they apply the cracks to the games that come as seperate ingredients in the original releases?

They do however usually make those releases smaller by compressing the shit out of them and making things like the additional media and language packs optional. And make the releases available through more mainstream avenues like torrents.

They exist for people with data caps and terribly slow internet. I’d argue they also exist for people with limited hdd space but you still need to decompress the game before you can play so instead you could say they are good for people that have seperate storage servers for their media libraries and backups.

You can keep an archive of all your downloaded pirated games that collectively take up half the space if you are the kind of person that hordes things like that, in case you decide you wanna reinstall and play a game again or something.
