What the heck! People who don't like MO, what are you talking about? Download, double-click, click, run the game - how easier can it be? If you love dump your game folder with bunch of files, do everything manually, spend hours of your life searching for errors and reinstalling, and pray Steam won't mess it up - then go do it, nobody makes you to use any mod manager. The only way to leave a game folder untouched is to trick the system into think the files are there - hence a virtual filesystem. Yes, it is a hack! So what? Everything is a hack if game is close-sourced. MO has been ingenious and a bliss for players who needed to manage massive mod collection and all these little mod patches. Tannin, and other devs, don't listen to anyone. It is really hard to please everybody's taste, do what you think is right. I wish you best of luck.
