Yer in my predicament, unfortunately. The download link has broken, and seems to have been broken for quite a long while now (years?) I, and others have complained but nothing is happening. Try out Rise from Erebus, it's a mod based on Fall Further I believe. In any case, it should have most, hopefully all, the features of Fall Further. Downloading it now.
Whilst I'm certainly not active in the Civ-modding community of late, having bowed out a few years past when my family was going through "a bit of a rough time" (which if I'm being perfectly frank, was a lot more important), I did pass by the forums just now so I will address the lack of functioning download link.
Basically, the mod was developed 5 years ago. The original source files for the mod were present on a hard drive that was in a PC 3 iterations ago (i.e. I've done 2 full rebuilds since then, the latest of which was from scratch). I suspect that somewhere around there is a hard drive with a copy of the files on, though I have no confidence in being able to find it. The link stayed functional as long as the original server it was hosted on did, which apparently no longer is the case.
You mentioned the RiFE mod as a possible alternative and I wholeheartedly agree with that suggestion. I did play some of that mod when I came across it (by which time it was already a good year or more into its development) and enjoyed it. I spoke with the creators, was invited to participate in their development forums and (for what it's worth) gave it my blessing. I very much enjoyed the world that Kael developed and the additions the community made to it through ModMods (a term I think I coined, but couldn't swear to it) so I was glad to see it continue from where I left it.
I did however also catch your comment, Eragi, in the download thread - something about "hating lazy mod developers" and "hoping the reason I hadn't updated was because I was dead". As it turns out, it wasn't actually me that died, which leaves me in a position to call you out for being the worst sort of self-entitled, reprehensible internet troll I've had the displeasure of coming across. The Modmod was a community effort (I was only responsible for the start of it and being "the face") half a decade ago and I suspect it's best that you missed it - you wouldn't have been welcome in the community I remember.
============
With that little bit of unpleasantness out of the way - I'll say "hello" to any of the old faces that are still around (the site tells me I last logged in September 2011, so I've been a little bit lax...)
I don't think I'm back in any active sense, but I do have a certain nostalgia for "the good old days".
