Axis by axis
Execution2 vs 1
Kingdom: Classic leans a little harder on execution, though the gap is small.
Kingdom: Classic
Riding left and right and dropping coins demands no twitch skill
X-COM: UFO Defense
Turn-based; only inventory clicking
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Kingdom: Classic
Greed waves follow scripted escalation, never adapt to you
X-COM: UFO Defense
Alien AI is scripted, never adaptive
Variance5 vs 6
X-COM: UFO Defense leans a little harder on variance, though the gap is small.
Kingdom: Classic
Unexplained mechanics and map layout are hidden until mapped
X-COM: UFO Defense
Hit rolls, random maps, and unseen aliens punish constantly
Optimization8 vs 8
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Kingdom: Classic
Coin economy and wall timing are the solvable core
X-COM: UFO Defense
Base economy, research order, and tactical doctrine are masterable
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.
