head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Reads · Bluff & Deduction
A couch crime thriller where players vote on the story while some pursue secret sabotage objectives.

Reads · Bluff & Deduction
A physics sandbox whose actual skill test is whatever board game you load into it.
Hidden Agenda leans Reads (Bluff & Deduction); Tabletop Simulator leans Reads (Bluff & Deduction).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Hidden Agenda
Phone-based QTEs are forgiving and rarely decisive.
Tabletop Simulator
Fiddly physics manipulation, never a skill ceiling
Hidden Agenda leans a little harder on reads, though the gap is small.
Hidden Agenda
Couch players with secret objectives bluff each other live.
Tabletop Simulator
Depends entirely on the tabletop game played with humans
Hidden Agenda leans a little harder on variance, though the gap is small.
Hidden Agenda
Hidden agendas and unknown story branches cloud decisions.
Tabletop Simulator
Dice and shuffled decks supply whatever randomness the game has
Hidden Agenda leans a little harder on optimization, though the gap is small.
Hidden Agenda
Branch knowledge from replays makes outcomes steerable.
Tabletop Simulator
Strategy lives in the hosted game, not the simulator
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
