head to head
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
A reverse tower defense testing convoy routing and unit composition against fixed defensive layouts.

Optimization · Pure Optimization
A landmark strategy game combining a turn-based campaign for control of Rome with massive real-time battles.
Anomaly 2 leans Optimization (Pure Optimization); Rome: Total War leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Anomaly 2
Steering the commander and ability drops needs light real-time hands
Rome: Total War
Real-time battle micro rewards quick unit handling
Anomaly 2 leans a little harder on reads, though the gap is small.
Anomaly 2
Tower-offense versus humans in multiplayer adds some prediction
Rome: Total War
Optional multiplayer battles; campaign AI is mappable
Rome: Total War leans a little harder on variance, though the gap is small.
Anomaly 2
Campaign tower layouts are fixed and learnable
Rome: Total War
Diplomacy and AI moves add modest fog
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Anomaly 2
Convoy composition, routing, and morph timing are the real test
Rome: Total War
Campaign economy, recruitment, and battle tactics are 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.
