head to head
Neither is simply harder - they are hard in different places. Grand Theft Auto: San Andreas demands more optimization; Teenage Mutant Ninja Turtles II: The Arcade Game demands more execution.

A sprawling open-world crime epic with RPG-style character stats across a whole state.

Execution · Practiced Mastery
Arcade brawler positioning and stamina against memorisable enemy waves.

Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Teenage Mutant Ninja Turtles II: The Arcade Game
