Axis by axis

Track building is grid-based with modest placement precision demands
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Portal 2
No opponent; puzzles are static.
RollerCoaster Tycoon 2
Guest behaviour follows fixed preference scripts
Variance0 vs 2
RollerCoaster Tycoon 2 leans clearly harder on variance.
Portal 2
Puzzles are deterministic with no randomness.
RollerCoaster Tycoon 2
Very little randomness once ride stats are understood
Optimization9 vs 9
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Portal 2
Solving the puzzle's logic IS the entire game.
RollerCoaster Tycoon 2
Pricing, ride stats, and park layout are near-perfectly solvable
