head to head
Empire: Total War asks more than LEGO Battles, and the gap is optimization.

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

Optimization · Pure Optimization
A simplified RTS testing basic build-order economy with light multiplayer prediction.
Empire: Total War leans Optimization (Pure Optimization); LEGO Battles leans Optimization (Pure Optimization).
LEGO Battles leans a little harder on execution, though the gap is small.
Empire: Total War
Real-time battle micro is modest
LEGO Battles
Stylus micro on DS is gentle, not twitch-defining
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Empire: Total War
Multiplayer line-battle feints exist
LEGO Battles
Multiplayer skirmishes add light human prediction
Empire: Total War leans a little harder on variance, though the gap is small.
Empire: Total War
Campaign AI and battle dice noise
LEGO Battles
Map fog and treasure hunts hide modest information
Empire: Total War leans clearly harder on optimization.
Empire: Total War
Campaign economy and line-infantry tactics are mappable
LEGO Battles
Build orders and base economy decide simplified RTS matches
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.
