Enemies scripted and predictable.
BioShock 2
Splicer AI scripted, not adaptive.
Variance2 vs 2
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed Valhalla
Loot rolls and raid encounters vary mildly.
BioShock 2
Sister-gathering waves add randomness.

Assassin's Creed Valhalla
Skill tree, gear, raid routing solvable.
BioShock 2
Plasmid combos and gear loadouts solvable.
