Mario & Luigi: Paper Jam leans Optimization (Pure Optimization); Portal 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.
Mario & Luigi: Paper Jam
Timed action commands reward but never gate progress
