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
The console FPS landmark that introduced Master Chief and the ring world.

Execution · Practiced Mastery
A top-down soccer game blending arcade play with deep team management.
Halo: Combat Evolved leans Execution (Practiced Mastery); Sensible World of Soccer '96/'97 leans Execution (Practiced Mastery).
Halo: Combat Evolved leans a little harder on execution, though the gap is small.
Halo: Combat Evolved
Aim, grenade timing, and vehicle control
Sensible World of Soccer '96/'97
Fast passing and shooting timing on the pitch matters
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Halo: Combat Evolved
Multiplayer duels reward reading humans
Sensible World of Soccer '96/'97
Versus play rewards predicting a human opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Halo: Combat Evolved
Covenant AI varies tactics slightly
Sensible World of Soccer '96/'97
Little randomness once ratings are known
Sensible World of Soccer '96/'97 leans a little harder on optimization, though the gap is small.
Halo: Combat Evolved
Weapon sandbox knowledge and encounter routing
Sensible World of Soccer '96/'97
Transfers, tactics and squad management deepen the career
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.
