head to head
Knights of the Old Republic asks more than Portal 2, and the gap is variance.

Optimization · Pure Optimization
A d20 Star Wars RPG where Force power selection and alignment routing define clear optimal paths.

Optimization · Pure Optimization
A first-person puzzle game where seeing the solution is the whole skill.
Knights of the Old Republic leans Optimization (Pure Optimization); Portal 2 leans Optimization (Pure Optimization).
Portal 2 leans a little harder on execution, though the gap is small.
Knights of the Old Republic
Pseudo-turn-based d20 combat removes all twitch; timing aids exist but minor
Portal 2
Portal placement requires some precision but timing is lenient.
Knights of the Old Republic leans a little harder on reads, though the gap is small.
Knights of the Old Republic
All enemies follow scripted AI behaviour trees without player modelling
Portal 2
No opponent; puzzles are static.
Knights of the Old Republic leans clearly harder on variance.
Knights of the Old Republic
Loot rolls and pazaak draws provide hidden information layers
Portal 2
Puzzles are deterministic with no randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Knights of the Old Republic
Force power selection, feat prerequisites and light/dark routing are systematically solvable
Portal 2
Solving the puzzle's logic IS the entire game.
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.
