head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Practiced Mastery
Open-world demolition testing combat execution and creative structural destruction planning.

Execution · Practiced Mastery
A classic arcade brawler sending the turtles through time to pummel Foot Clan waves.
Red Faction: Guerrilla Re-Mars-tered leans Execution (Practiced Mastery); Teenage Mutant Ninja Turtles IV: Turtles in Time leans Execution (Practiced Mastery).
Teenage Mutant Ninja Turtles IV: Turtles in Time leans a little harder on execution, though the gap is small.
Red Faction: Guerrilla Re-Mars-tered
Hammer swings, driving and firefights under EDF pressure need hands
Teenage Mutant Ninja Turtles IV: Turtles in Time
Throw timing, positioning, and boss dodges are the whole test.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Red Faction: Guerrilla Re-Mars-tered
EDF response is scripted escalation, not adaptation
Teenage Mutant Ninja Turtles IV: Turtles in Time
Foot Soldiers run fixed scripts.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Red Faction: Guerrilla Re-Mars-tered
Open world is fixed once explored
Teenage Mutant Ninja Turtles IV: Turtles in Time
Stages and waves are essentially fixed.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Red Faction: Guerrilla Re-Mars-tered
Choosing demolition approaches and upgrade routes rewards planning
Teenage Mutant Ninja Turtles IV: Turtles in Time
Wave layouts and boss patterns are fully memorisable.
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.
