Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Resident Evil Revelations 2
First-run scares, unknown layouts, raid mode loot rolls.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Stats, gym, weapon skill, and routes reward systematic play
Resident Evil Revelations 2
Resource routing, enemy spawn knowledge, episode mastery once mapped.
