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

Optimization · Pure Optimization
Turn-based mech tactics where lance builds and heat math decide drawn-out slugfests.

Optimization · Pure Optimization
A first-person puzzle game where seeing the solution is the whole skill.
BattleTech leans Optimization (Pure Optimization); Portal 2 leans Optimization (Pure Optimization).
Portal 2 leans clearly harder on execution.
BattleTech
Turn-based; no physical inputs matter
Portal 2
Portal placement requires some precision but timing is lenient.
BattleTech leans a little harder on reads, though the gap is small.
BattleTech
AI lances follow exploitable scripted behavior
Portal 2
No opponent; puzzles are static.
BattleTech leans clearly harder on variance.
BattleTech
To-hit rolls and component crits swing fights
Portal 2
Puzzles are deterministic with no randomness.
Portal 2 leans a little harder on optimization, though the gap is small.
BattleTech
Mech builds, heat management, and initiative play
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.
