I'd say a successful mod is only for the mod author to choose. I believe they have the choice to think whether or not their mod is successful. Like they say. "Beauty is in the eye of the beholder." Sure, there could be 50 people who review a mod. Sure half could be good reviews, the other half bad reviews. But it doesn't matter. A mod could have only 15 downloads when it's been out for four years, so what? As long as the mod author feels like they produced a good mod, then it's successful. For me personally, I consider all of my mods a success because I mod on a Mac. Sure, I have to run the same PC applications as everyone else, but they're a pain to get working sometimes and don't always work correctly. I just find them successful because everyone says Macs are horrible, or you can't do anything that a PC can do. Well, I'm here to prove that wrong in a modding sense. I (or anyone as a modder) shouldn't care about what people think of your mods. They're YOUR mods, YOU made them, and you should be happy about that. It doesn't matter the content of the mod, it could be a lightsaber mod, an armor mod, or a whole module. Again, I feel it just depends on what the author thinks of their stuff. I will always find my mods to be successful, even if they have 10 downloads. I don't care, they're mine, and I'm glad for that. I know I kind of went too into my own mods, but that's just the general concept that I'm trying to get out.
