Of the urban fantasy games that have come out in the last three decades or so, the one that seems to dominate the market is
World of Darkness. Well, that and
Shadowrun. I could be wrong, that's the impression I get. What sets
World of Darkness apart from something like
Dungeons & Dragons,
All Flesh Must be Eaten,
Urban Shadows,
Monsterhearts, or
Feed is that it isn't a "generic" game which supports a variety of settings. It has a three decade old convoluted comic-book style continuity baked in.
The less said about the mechanics the better. Especially the superpowers. It you want my opinion at its most succinct, then I believe a mechanic like
Godbound's words is vastly superior to the mess that is
World/
Chronicles of Darkness.
I find all that rather grating. I don't like
World/
Chronicles of Darkness because I don't like being restricted to play in someone else's arbitrarily narrow sandbox. I don't like playing a game that is firmly stuck in an early 90s zeitgeist when the urban fantasy genre is so much more diverse than that and roleplaying games have expanded so far in that time. I like having loads of options, like how
Dungeons & Dragons has a bazillion campaign settings both official and third-party.
There simply doesn't seem be any game approximating
Dungeons & Dragons's diversity for the urban fantasy genre, or at least none that have achieved anywhere near as much success as
World of Darkness.
