head to head
Final Fantasy Tactics asks more than Portal 2, and the gap is variance.

Optimization · Pure Optimization

Optimization · Pure Optimization
A first-person puzzle game where seeing the solution is the whole skill.
Final Fantasy Tactics leans Optimization (Pure Optimization); Portal 2 leans Optimization (Pure Optimization).
Portal 2 leans a little harder on execution, though the gap is small.
Final Fantasy Tactics
No twitch; CT-tick positioning demands spatial planning only
Portal 2
Portal placement requires some precision but timing is lenient.
Final Fantasy Tactics leans a little harder on reads, though the gap is small.
Final Fantasy Tactics
CPU job/action selection is fixed and fully predictable
Portal 2
No opponent; puzzles are static.
Final Fantasy Tactics leans clearly harder on variance.
Final Fantasy Tactics
Random drops and some proc rates exist but rarely swing outcomes
Portal 2
Puzzles are deterministic with no randomness.
Final Fantasy Tactics leans a little harder on optimization, though the gap is small.
Final Fantasy Tactics
Job mastery, ability stacking, and CT manipulation are near-perfectly 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.
