head to head
M1 Tank Platoon asks more than Portal 2, and the gap is variance.

Optimization · Pure Optimization
A tank combat sim mixing direct gunnery with platoon-level tactical command.

Optimization · Pure Optimization
A first-person puzzle game where seeing the solution is the whole skill.
M1 Tank Platoon leans Optimization (Pure Optimization); Portal 2 leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
M1 Tank Platoon
Aiming the tank gun matters but isn't twitch-decisive
Portal 2
Portal placement requires some precision but timing is lenient.
M1 Tank Platoon leans clearly harder on reads.
M1 Tank Platoon
Enemy AI is scripted, not adapting to you
Portal 2
No opponent; puzzles are static.
M1 Tank Platoon leans clearly harder on variance.
M1 Tank Platoon
Fog-of-war and scripted-unknown enemy positions
Portal 2
Puzzles are deterministic with no randomness.
Portal 2 leans a little harder on optimization, though the gap is small.
M1 Tank Platoon
Platoon coordination and tactical positioning win battles
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.
