head to head
League of Legends asks more than Supreme Commander 2, and the gap is reads.

Reads · Grand Arena
A team MOBA where map control and adaptive duels decide objectives.

Optimization · Grand Arena
Large-scale RTS testing economic optimization, multitask speed and prediction of human build choices.
League of Legends leans Reads (Grand Arena); Supreme Commander 2 leans Optimization (Grand Arena).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
League of Legends
Mechanics matter but not aimbot-decisive.
Supreme Commander 2
Macro APM across huge armies separates skirmish winners
League of Legends leans clearly harder on reads.
League of Legends
Lane and jungle constantly mind-game opponents.
Supreme Commander 2
Multiplayer rewards scouting and predicting a human's tech switches
League of Legends leans a little harder on variance, though the gap is small.
League of Legends
Champion select and minor RNG only.
Supreme Commander 2
Open maps leave little hidden beyond fog of war
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
League of Legends
Itemization, wave management, and macro are solvable.
Supreme Commander 2
Economy ratios, build orders and research routing are deeply solvable
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.
