So, I'm wondering - what goes into your decision of whether to download or try a mod? What are the greatest influencing factors?
I like stuff that blends in well with the game. Mods that don't jar you the moment you find the content and make you say "yep, mod". I gravitate toward village and city improvements, so anything along those lines that's done well but not over the top is where I look first. As a natural extension, it's where I focus most of my own modding energies too.
I'm also a fan of good quest mods that also fit in nicely and provide significant new content. There's plenty of quest mods out there that just don't fit that bill for me and so I pass on them.
Weapon and armor mods tend to generate little interest from me since the vast majority of them feel out of place with the rest of the game. Those I do use blend in and are done well enough that it doesn't stand out.
Magic overhauls generate no interest for me since my play style clashes with magic in general. So it can be the greatest overhaul of magic in history and my reaction at best is "meh".
As a contrast, anything favoring brute force or stealth related characters I'll take a look at.
In general, as long as a mod is well presented and it looks like the author cares enough to maintain it and handle support, a mod usually does pretty well.
Your particular set of mods, while they look well done, are just not areas of the game I'm interested in modifying.
You need to be patient and wait a bit longer to see if your mod is going to pick up before getting frustrated that it's not popular enough. It could simply be that you're serving a niche market, much like I am with village mods, and you may never see huge numbers. It doesn't mean your mods svck, it just means they appeal to a specific type of player.
