Primordia
Optimization · Pure Optimization
A post-apocalyptic robot adventure built on dense lore and logical machine puzzles.
Plants vs. Zombies leans Optimization (Pure Optimization); Primordia leans Optimization (Pure Optimization).
Plants vs. ZombiesPrimordia
Axis by axis
Execution1 vs 1
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Plants vs. Zombies
Clicking to plant, minimal pressure
Primordia
Pure pointing and clicking, no dexterity
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Plants vs. Zombies
Zombie waves follow set compositions
Primordia
No adaptive opponent
Variance3 vs 3
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Plants vs. Zombies
Wave timing and lane pressure vary mildly
Primordia
Unknown solutions first time; nothing random
Optimization8 vs 8
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Plants vs. Zombies
Sun economy and lane setups are near-solvable
Primordia
Logic puzzles are fixed and fully 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.
