head to head
Neither is simply harder - they are hard in different places. LMA Manager 2007 demands more variance; Portal 2 demands more execution.

Optimization · Pure Optimization

Optimization · Pure Optimization
A first-person puzzle game where seeing the solution is the whole skill.
LMA Manager 2007 leans Optimization (Pure Optimization); Portal 2 leans Optimization (Pure Optimization).
Portal 2 leans clearly harder on execution.
LMA Manager 2007
no direct execution, pure management sim
Portal 2
Portal placement requires some precision but timing is lenient.
LMA Manager 2007 leans a little harder on reads, though the gap is small.
LMA Manager 2007
AI managers scripted, minimal true adaptivity
Portal 2
No opponent; puzzles are static.
LMA Manager 2007 leans clearly harder on variance.
LMA Manager 2007
match simulation outcomes carry randomness
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.
LMA Manager 2007
tactics, transfers, and finances are deeply 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.
