As a few people in the comments point out, elemental affinities and Doom resistances are nothing like RPS. (Also if you're guessing elemental affinities in most games, you're doing it wrong. Scan more if it isn't obvious innately.) That's more a matter of "using what works best".
Also, it's pretty ridiculous to have a RPS in video games discussion without bringing in things like fighting games and competitive Pokemon which have really applicable parallels.
