What makes HP feel different from Harm? It is essentially the same in my head. I also really like that in Dungeon World, that the game isn’t bogged down by what weapon does the most damage. It is all in the characters capabilities.

I haven’t looked at every hack of Dungeon World. But they all slightly changes some of the moves here and there. Either in ways I like or not.

Homebrew World has a slightly different take on inventory and the defend move I really enjoy. But it still uses spell lists. But it is more or less my go-to for one-shots due to it having much less mechanics.

I really liked Worlds of Adventure new stats (the unpublished version) and that race no longer has a hard mechanic behind it. But Wizards still use a spell list.

Unlimited Dungeons has a neat mechanic for wizard spells, but I find it still quite limiting an rigid. Its heritage mechanic is neat, but I do not like its “mark box to use ability”-aspect. But if the heritage aspect is removed, it is a nice hack.

My favorit is my own hack, Mixed Adventures, which combines the various aspects I enjoy from the hacks. The most unique part of it is how it handles spell casting which isn’t a fixed list. The character chooses couple aspects for their magic (spheres/domain) that determine what they can do with their magic. The player simply describes a spell that fits. And if it seems like to much, the GM may add requirements or say it must be a ritual (ala Monster of the Week).
