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.

Optimization · Mind & Math
14-epoch RTS where economic scaling, epoch-rush timing, and civilization counter-picks span stone age to future war.

Reads · Grand Arena
Team prediction and macro optimisation compressed into touch-screen MOBA matches.
Empire Earth leans Optimization (Mind & Math); League of Legends: Wild Rift leans Reads (Grand Arena).
League of Legends: Wild Rift leans a little harder on execution, though the gap is small.
Empire Earth
Epoch-spanning army micro and hero management need consistent attention
League of Legends: Wild Rift
Touch-screen skillshots and kiting still set a real ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Empire Earth
Opponent epoch rush and civilization bonuses must be predicted
League of Legends: Wild Rift
Outguessing human laners and junglers never stops
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Empire Earth
Map resource distribution adds uncertainty at start; converges quickly
League of Legends: Wild Rift
Drake spawns and crit rolls add bounded noise
Empire Earth leans a little harder on optimization, though the gap is small.
Empire Earth
Epoch advancement timing and citizen allocation are near-optimally solvable
League of Legends: Wild Rift
Builds, wave control and objective timing 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.
