head to head
Naruto Shippuden: Ultimate Ninja Storm Revolution asks more than Pong, and the gap is optimization.

Execution · Competitive PvP
Simple-input arena fighting decided by baiting human defensive resources.

Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Naruto Shippuden: Ultimate Ninja Storm Revolution

Naruto Shippuden: Ultimate Ninja Storm Revolution leans a little harder on variance, though the gap is small.
Naruto Shippuden: Ultimate Ninja Storm Revolution
Fully visible fights with nothing hidden
Pong
Fully deterministic ball physics
Naruto Shippuden: Ultimate Ninja Storm Revolution leans clearly harder on optimization.
Naruto Shippuden: Ultimate Ninja Storm Revolution
Team and awakening type picks are a shallow solvable layer
Pong
