Not sure how good this really is, but I liked it well enough to read it from chapter 1 all the way to its current endpoint -- which is chapter 32 after almost 180,000 words. Had never heard of this story before I started reading it.

Ranma gets caught up in the adventure of a lifetime, surrounded by girls, fighting for the fate of the world, and occasionally gets splashed with water. Sounds like a regular day for Ranma? Except there's no such thing as a regular day for Ranma, because he's starting out in Midgar. Ranma 1/2 X FF7

Hasn't been updated in a while but it went from zero to current in a bit over fourteen months and the author updated their profile in April so there is some hope.
If anyone else likes it, fine, if no one else does, no big deal.
