I'm looking to create a mod for skyrim and I am wanting to create it with c++. I want to create a mod for the actual game itself (like modifying the game's game files) and not creating a plugin for SKSE or ENB. Is it possible? This has to be done in c++. And has to be a mod for the actual game.

Thanks, Techquickie.

You cannot modify the exe.

You can create code plugins (like SKSE), or mod plugins with the Creation Kit.
