head to head
Thronefall asks more than Portal 2, and the gap is variance.

Optimization · Pure Optimization
A first-person puzzle game where seeing the solution is the whole skill.

Optimization · Pure Optimization
Minimalist build-order puzzles defended with light real-time positioning.
Portal 2 leans Optimization (Pure Optimization); Thronefall leans Optimization (Pure Optimization).
Thronefall leans a little harder on execution, though the gap is small.
Portal 2
Portal placement requires some precision but timing is lenient.
Thronefall
Kiting and positioning your lord at night takes modest control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Portal 2
No opponent; puzzles are static.
Thronefall
Waves are previewed and scripted, never adaptive
Thronefall leans clearly harder on variance.
Portal 2
Puzzles are deterministic with no randomness.
Thronefall
Minimal randomness; wave compositions are shown
Portal 2 leans a little harder on optimization, though the gap is small.
Portal 2
Solving the puzzle's logic IS the entire game.
Thronefall
Build order and perk loadouts decide every map
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.
