head to head
Super Puyo Puyo 2 asks more than Dead Space 3, and the gap is reads.

Execution · Practiced Mastery
A crafting-heavy survival shooter where weapon-build optimisation and aimed dismemberment carry the loop.

Execution · Practiced Mastery
A competitive falling-block puzzle about building chains under speed and opponent pressure.
Dead Space 3 leans Execution (Practiced Mastery); Super Puyo Puyo 2 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Space 3
Weapon crafting alters execution demands but shooting stays central
Super Puyo Puyo 2
Fast piece placement under accelerating drop is core
Super Puyo Puyo 2 leans clearly harder on reads.
Dead Space 3
All enemies scripted; co-op adds coordination not prediction
Super Puyo Puyo 2
Versus mode adds light anticipation of opponent chains
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
Super Puyo Puyo 2
Piece order is random but quickly mappable
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Space 3
Deep weapon crafting system rewards systematic optimisation
Super Puyo Puyo 2
Building large chain combos is the deep skill
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
