Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Optimization · Pure Optimization
Gunpowder-era Total War blending empire management with line battles.

Optimization · Pure Optimization
An oriental-fantasy grind MMORPG where upgrade luck and farming efficiency define progress.

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Empire: Total War
Real-time battle micro is modest
Metin2
Hack-and-slash grinding with simple inputs.
Empire: Total War leans a little harder on reads, though the gap is small.
Empire: Total War
Multiplayer line-battle feints exist
Metin2
Kingdom wars add light player-versus-player conflict.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Empire: Total War
Campaign AI and battle dice noise
Metin2
Upgrade chance rolls dominate gear progression.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Empire: Total War
Campaign economy and line-infantry tactics are mappable
Metin2
Farming spots, alchemy, and stat builds are solvable grind.
