Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
Medieval: Total War leans Optimization (Pure Optimization); Portal leans Optimization (Pure Optimization).
Portal leans a little harder on execution, though the gap is small.
Medieval: Total War
Real-time battle control rewards quick unit handling
Portal
Portal placement timing modest.
Medieval: Total War leans clearly harder on reads.

Multiplayer battles add human feints; campaign AI is scripted
Portal
No adversary modeling player.
Medieval: Total War leans clearly harder on variance.
Medieval: Total War
Battle dice, loyalty and event cards add noise
Portal
Deterministic chambers; no randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Medieval: Total War
Campaign economy and battlefield doctrine are deeply learnable
Portal
Pure puzzle-solving optimization.
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.
