No opponent; puzzles are static.
RollerCoaster Tycoon
Guests are simple, fully mappable simulations

Guest spawns and breakdowns barely matter
Optimization9 vs 9
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Solving the puzzle's logic IS the entire game.
RollerCoaster Tycoon
Park layout, pricing, and coaster stats are solvable systems
