On a similar note: on Steam, the original Dark Souls game[1] is listed with the "souls-like" tag. That's not wrong, I guess, but just kind of a tautology. Grice's maxims[2] generally have such tautologies omitted in ordinary conversation as non-informative.

For me it is surprisngly natural to include the original thing into "a set of thing-likes".

Why does it feel wrong (or meaningless) to you?
