For The One Ring I just run a discord server with the Narvi bot, although I run combat, journeys and counsils myself because I couldn’t be bothered learning the contexts and such.
For any duet sessions with my SO (we’ve done Mothership and Delta Green) we just call each other over Whatsapp or Signal and I trust her not to cheat the rolls, then we track everything on pen and paper ourselves. It works pretty great for how ultra minimalistic it is

More stuff to kill in the kill stuff game. If you look at games that emphasize more narrative, there will be fewer pages dedicated to just monsters, like The One Ring 2e. The downside is having less varied combat and less freedom on crafting your own stuff
