I would kill for this mod!
Cause I too would infinitely prefer to just have one character. I hate being stuck with two, even though I can leave one behind in town, there's still dialogue issues to deal with and yeah 'the whole thing'...
I really wish I could make this mod myself, but it's just way beyond me. So I live in hope that some talented soul will figure out how to do this.
I have a little idea for a story based around stealth gameplay, but it involves just one character. Having two character, or worse yet, a whole party, just wouldn't work for what I have in mind
So all we can do is hope that one of the incredibly clever folks around here (yeah, I'm crawling) like solo gameplay too
