There were some LotR maps in WC3, exactly how you describe them. I've never really enjoyed them, but my brother played them a lot. Can't remember the names either, unfortunately.
Some of them were straight up LotR maps, still. Handful based on Warcraft lore (Azeroth Wars comes to mind; if for some reason you want to watch people play it, there's at least a few dozen hours of gameplay vids on youtube), some on other franchises or original stuff. Occasionally based on real life, though those tended to be more in the direction of civ-like stuff.
There's a good... at least six or seven, maybe a dozen or more, maps of that sort that were top tier-ish so far as WC3 went, though. Did about as good a job as possible in WC3 and still able to be played online, heh. Half want to say there's still one or two getting the occasional update, even.
Fate is still around. Could never get in to it, a little too cartoony for me after cracking out for a good hundred hours in Diablo.
Iirc the devs went on to make the torchlight games, which've ended pretty alright as that sort of style of game goes.
I remember fate pretty well, and fairly unpleasantly, heh. Somehow managed to be more grindy than diablo was (and not really in a good way), and the combat always felt sorta' clunky, problems more mechanical than aesthetic, for me. Had at least one good idea, though, with the way it handled pet vender trash management. Not as good a one on that front as, say, the latest ToME, but it was a nice QoL improvement at the time regardless.
