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

Optimization · Systems & Chaos
The classic WWII Pacific submarine simulator of stalking Japanese convoys and plotting torpedo attacks.

Optimization · Systems & Chaos
A physics sandbox where you place wobbly armies and watch ragdoll battles resolve themselves.
Silent Service leans Optimization (Systems & Chaos); Totally Accurate Battle Simulator leans Optimization (Systems & Chaos).
Silent Service leans a little harder on execution, though the gap is small.
Silent Service
Periscope aiming and timing matter, but pace is slow
Totally Accurate Battle Simulator
Place units then watch; no hands required
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Silent Service
Escort AI is scripted; no adaptive opponent
Totally Accurate Battle Simulator
No adaptive opponent in campaign sandbox
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Silent Service
Convoy composition and detection rolls are hidden randomness
Totally Accurate Battle Simulator
Wobbly physics makes identical setups resolve differently
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Silent Service
Torpedo solutions and approach plotting are solvable geometry
Totally Accurate Battle Simulator
Unit counters and placement solve each scenario
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.
