head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Pure Optimization
Turn-based tactics where movement combos turn battles into solvable puzzles.

Optimization · Pure Optimization
A post-apocalyptic robot adventure built on dense lore and logical machine puzzles.
Mario + Rabbids Kingdom Battle leans Optimization (Pure Optimization); Primordia 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.
Mario + Rabbids Kingdom Battle
Turn-based; no dexterity gate
Primordia
Pure pointing and clicking, no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mario + Rabbids Kingdom Battle
Enemy AI follows predictable rules
Primordia
No adaptive opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mario + Rabbids Kingdom Battle

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mario + Rabbids Kingdom Battle
Movement chains and team-jump routing are puzzle-solvable
Primordia
Logic puzzles are fixed and fully solvable
