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

Execution · Practiced Mastery
A destruction-driven military shooter where squads level buildings around objectives.

Execution · Practiced Mastery
A kart racer testing driving precision and item management on user-created tracks.
Battlefield: Bad Company leans Execution (Practiced Mastery); ModNation Racers: Road Trip 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.
Battlefield: Bad Company
Vehicle and infantry gunskill across big maps
ModNation Racers: Road Trip
Drifting and boosting at speed demands driving precision
Battlefield: Bad Company leans a little harder on reads, though the gap is small.
Battlefield: Bad Company
Predicting human squad pushes on objectives
ModNation Racers: Road Trip
Versus humans, anticipating weapon use matters somewhat
ModNation Racers: Road Trip leans a little harder on variance, though the gap is small.
Battlefield: Bad Company
Destruction and large lobbies create chaos
ModNation Racers: Road Trip
Item pickups and weapon spread add kart-racer chaos
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Battlefield: Bad Company
Class roles and objective flow are learnable
ModNation Racers: Road Trip
Track lines, boost management and shortcuts reward planning
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.
