Shadow of the Demon Lord is another obvious choice, and I'm kind of ashamed that I forgot about it. SotDL is basically the love child of Warhammer Fantasy and D&D 5e, with flairs of the Diablo game franchise.Warhammer FRPG, which is basically the grandfather game Zweihander is based on.
Shadows of the Demon Lord, seems a scent choice as well, though I had not played much of it personally.
Midnight (3.5): Midnight: 2nd Edition Core Rulebook - EDGE Studio | DriveThruRPG.com
5E version coming next year: Midnight
How about we wait and see the final result before judging? Cubicle 7 stripped down many of the "superpowers" from their Adventures in Middle-Earth 5E classes, perhaps Edge will do the same for Midnight 5e.I don't see the system and setting meshing. Midnight is about battling against incredible odds, a LotR where Sauron got the One Ring.
But 5e is about building super-powered PCs. Not a good fit.
