head to head
FIFA Soccer 11 asks more than Tecmo Bowl, and the gap is execution.

Execution · Competitive PvP
Football sim testing stick execution and reading a human opponent's tactical habits.

Reads · Competitive PvP
A four-play guessing duel where picking the opponent's call wins drives.
FIFA Soccer 11 leans Execution (Competitive PvP); Tecmo Bowl leans Reads (Competitive PvP).
FIFA Soccer 11 leans clearly harder on execution.
FIFA Soccer 11
Pass timing, dribbling and finishing demand stick skill
Tecmo Bowl
Stick skill on runs and dives matters but stays simple
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
FIFA Soccer 11
Human opponents' defensive habits and attacking patterns must be modelled
Tecmo Bowl
Guessing the opponent's one play call is the famous mind-game
FIFA Soccer 11 leans a little harder on variance, though the gap is small.
FIFA Soccer 11
Deflections and keeper behaviour add bounded chaos
Tecmo Bowl
Outcomes wobble on tackle rolls but little stays hidden
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
FIFA Soccer 11
Formations, tactics and squad knowledge shape matches
Tecmo Bowl
Roster strengths and play-call odds are quickly solved
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.
