Thank you for your replies. I am now certain that I want to play MM3 to MM5 first, and then the mods.

Do you know if the mods will work with the GOG versions of MM6 and MM7?

Now that I think about it I have played some mod of MM7 that has only the light path, but also gave master dark magic near the end. Is this the same mod you mentioned?

Thanks again
