Pirated Games

There's no real nice way to say this, so I'll be direct. This is one of the most basic questions you could ask in a piracy community, reveals a lack of effectively any attempt to read up on things and understand them on your own, and it is written like you don't have a good grasp on English.

Of course cracked games aren't original. Why are you specifying that as though it's important?

There is no way to play a game protected by DRM without either buying it properly to allow you through the DRM legitimately, or using a cracked copy to remove/bypass that DRM.

You can see if there is a version sold on GoG, as all releases through GoG are DRM free. On that case you can just download the unmodified GoG installer from a third party and install the unmodified/original DRM free version.

Beyond that, you will have to deal with the DRM. We could get in the weeds about some of the specifics of how different DRM can be bypassed in different ways, but it will always involve at minimum an addition to the game's files, and usually further changes to the executable to remove DRM related code. That's not something you'd do yourself, you'd just get an already cracked copy from a safe source.

Ultimately, this whole "original, non cracked copy" is kind of a nonsense concern. There's only a few mods on Nexus that do any sort of checking for if the game is a legitimate copy. Likewise for mods that claim to truly, absolutely require an unmodified copy of the game. Usually that just means that you shouldn't use that mod on top of another mod. As long as you are downloading your pirated copy from a safe source, overwhelmingly you'll be able to mod it with stuff from Nexus.

If you start having issues, just do your research before you report the issue to the developer of the mod to make sure it's not a crack related problem. Most mods with that will be specific about it somewhere easily found. And don't openly tell people you're using a cracked version when asking for help.

Additionally, since you're asking such a simple question, I'll give some extra info: In general, you will not have access to multiplayer features with a pirated/cracked game. You absolutely won't have access to Steam based features like achievements or mods from the Steam Workshop (if the game supports that).
