Broken Sword: The Sleeping Dragon
light action segments, mostly puzzle-paced
Portal 2
Portal placement requires some precision but timing is lenient.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Broken Sword: The Sleeping Dragon
no adaptive antagonist present
Portal 2
No opponent; puzzles are static.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.

Broken Sword: The Sleeping Dragon
item and dialogue logic puzzles
Portal 2
