I'd say this game is more mod friendly than most. In fact in the 1.1 patch soon to be released they have increased the number of capital ships you can add for modding purposes. I think many are probably waiting for the 1.1 patch before they update their mods.
I know exactly what you mean though. Look at mount & blade. It has a ton of mods but they are spread out across versions. I have 3 versions of the software installed just so I could try out the different mods.
