head to head
Replica asks more than Still Life, and the gap is variance.

Variance · Systems & Chaos
Surveillance-state deduction from hidden information inside a stranger's phone.

Optimization · Pure Optimization
Uncovering a fixed murder mystery through inventory puzzles and deduction.
Replica leans Variance (Systems & Chaos); Still Life leans Optimization (Pure Optimization).
Still Life leans a little harder on execution, though the gap is small.
Replica
Tapping a simulated phone needs no skill
Still Life
Pointing and clicking carries no physical demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Replica
The state's demands follow a fixed script
Still Life
The killer is a fixed narrative, not an adapting opponent
Replica leans clearly harder on variance.
Replica
Passwords and incriminating clues are hidden until cross-referenced
Still Life
The mystery's facts are hidden until uncovered
Still Life leans a little harder on optimization, though the gap is small.
Replica
Deduction from phone contents has discrete solutions per ending
Still Life
Inventory puzzles and deduction steps have fixed solutions
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.
