head to head
Mario Kart 7 asks more than Grand Theft Auto: San Andreas, and the gap is execution.

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.
