For ease of modding, it is about as easy as SEIV is. The data files are all text based data files, and you only have to open them with notepad or word pad, and make the changes you want. The dificulty comes in how much you want to change, and what you want to change - for extensive changes it may be a little time consuming and tedious - there are a few files to make modding easier, but so far all of the changes I have done have been just as easier or easier to do in wordpad.

As for how moddable it is; I think that it actually has more capabilities for modding than SEIV does.
