Portal 2vsRaft
Neither is simply harder - they are hard in different places. Portal 2 demands more optimization; Raft demands more variance.
Portal 2
Optimization · Pure Optimization
A first-person puzzle game where seeing the solution is the whole skill.
Raft
Optimization · Pure Optimization
Growing a floating base by solving resource chains and research order against scripted ocean threats.
Portal 2 leans Optimization (Pure Optimization); Raft leans Optimization (Pure Optimization).
Portal 2Raft
Axis by axis
Execution3 vs 2
Portal 2 leans a little harder on execution, though the gap is small.
Portal 2
Portal placement requires some precision but timing is lenient.
Raft
Shark hook-attacks require minimal timing
Reads0 vs 0
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.
Raft
Shark and seagull AI are scripted with no player modelling
Variance0 vs 4
Raft leans clearly harder on variance.
Portal 2
Puzzles are deterministic with no randomness.
Raft
Island loot tables and resource drift introduce randomness
Optimization9 vs 7
Portal 2 leans clearly harder on optimization.
Portal 2
Solving the puzzle's logic IS the entire game.
Raft
Raft expansion, food chains, and research order are solvable systems
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.
