Dead Space 3 leans Execution (Practiced Mastery); Puyo Puyo Fever 2 leans Execution (Practiced Mastery).
Puyo Puyo Fever 2 leans a little harder on execution, though the gap is small.

Puyo Puyo Fever 2 leans clearly harder on reads.
Dead Space 3
All enemies scripted; co-op adds coordination not prediction
Puyo Puyo Fever 2

Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Space 3
Scavenger bot loot adds mild RNG to crafting resources

Piece colors random but quickly mapped
Dead Space 3 leans a little harder on optimization, though the gap is small.
