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 · Pure Optimization
A third-person tower defense about funneling orc hordes into gleefully lethal trap corridors.

Optimization · Pure Optimization
A watercolor tactical RPG mixing turn-based command with real-time aiming.
Orcs Must Die! leans Optimization (Pure Optimization); Valkyria Chronicles leans Optimization (Pure Optimization).
Orcs Must Die! leans a little harder on execution, though the gap is small.
Orcs Must Die!
Active shooting supplements the traps
Valkyria Chronicles
Manual third-person aiming inside turns helps
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Orcs Must Die!
Orc waves follow fixed paths
Valkyria Chronicles
Enemy AI is scripted and exploitable
Valkyria Chronicles leans a little harder on variance, though the gap is small.
Orcs Must Die!
Minor wave composition randomness
Valkyria Chronicles
Accuracy rolls and interception fire add noise
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Orcs Must Die!
Trap placement and kill-corridor economics are the game
Valkyria Chronicles
Unit positioning, class use, and turn routing dominate
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.
