Enslaved: Odyssey to the West Premium Edition
A linear journey with little hidden
Grand Theft Auto V
Some mission and lobby randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Upgrade picks and encounter approaches add light depth
