head to head
Heavy Rain asks more than The Stanley Parable: Ultra Deluxe, and the gap is execution.

Execution · Light / Casual

Heavy Rain leans clearly harder on execution.
Heavy Rain
QTE prompts under tension
The Stanley Parable: Ultra Deluxe
Walking and clicking, no mechanical demand.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Heavy Rain
No adaptive opposition
The Stanley Parable: Ultra Deluxe
Narrator is scripted, not adaptive.
Heavy Rain leans a little harder on variance, though the gap is small.
Heavy Rain
First-run uncertainty about consequences
The Stanley Parable: Ultra Deluxe
Hidden endings to discover.
Heavy Rain leans a little harder on optimization, though the gap is small.
Heavy Rain
Branch knowledge fully solves outcomes
The Stanley Parable: Ultra Deluxe
Mapping ending tree rewards completionists.
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.
