head to head
VRChat asks more than Firewatch, and the gap is reads.

Optimization · Light / Casual
A first-person mystery about a fire lookout in a Wyoming forest.

Reads · Light / Casual
A social platform that tests presence and people skills, not gameplay mastery.
Firewatch leans Optimization (Light / Casual); VRChat leans Reads (Light / Casual).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Firewatch
Walking and radio dialogue only.
VRChat
Socialising and exploring demand no mechanical skill
VRChat leans clearly harder on reads.
Firewatch
No adaptive opposition.
VRChat
Reading other humans socially, not competitively
VRChat leans a little harder on variance, though the gap is small.
Firewatch
Minor environmental discoveries.
VRChat
User-generated worlds surprise but aren't a skill test
Firewatch leans a little harder on optimization, though the gap is small.
Firewatch
Few systems to optimize.
VRChat
No win condition to optimise toward
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.
