Bad PiggiesvsPortal
Portal asks more than Bad Piggies, and the gap is execution.
Bad Piggies
Optimization · Pure Optimization
Tests physics contraption engineering against fixed puzzle levels.
Portal
Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
Bad Piggies leans Optimization (Pure Optimization); Portal leans Optimization (Pure Optimization).
Bad PiggiesPortal
Axis by axis
Execution2 vs 4
Portal leans clearly harder on execution.
Bad Piggies
Light steering of contraptions after building
Portal
Portal placement timing modest.
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Bad Piggies
No opponent of any kind
Portal
No adversary modeling player.
Variance1 vs 0
Bad Piggies leans a little harder on variance, though the gap is small.
Bad Piggies
Levels are fixed and repeatable
Portal
Deterministic chambers; no randomness.
Optimization7 vs 8
Portal leans a little harder on optimization, though the gap is small.
Bad Piggies
Contraption engineering for three-star solutions is the game
Portal
Pure puzzle-solving optimization.
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.
