SimTower

SimTower began in Japan as The Tower, designed by Yoot Saito at OPeNBooK and released there in 1994. Will Wright — SimCity's creator — mentioned it to Maxis president Jeff Braun, and Maxis licensed it for worldwide release, publishing it in November 1994 for Windows and Mac as SimTower: The Vertical Empire to ride the Sim-franchise brand. The rebadge hid an obsessive little secret: the game was literally built around an elevator simulation. Saito had even contacted an elevator company to learn real scheduling techniques — they declined to share — and that fixation became the whole game's DNA.

You built up to 100 floors above ground and 9 below, filling them with offices, condos, hotels, restaurants, and shops while your tower climbed a one-to-five-star rating; crown a completed five-star build with a cathedral and it achieved the coveted "Tower" status. But the real game was vertical traffic. Tiny tenants queued in lobbies, flashed red with impatience when the wait stretched, and moved out if you'd botched the elevator scheduling — so players spent hours tuning express shafts and floor assignments, restarting after catastrophic rush-hour congestion cascades. It was meditative and infuriating in equal measure: the specific, neurotic satisfaction of a system running just right.

Saito followed it with Yoot Tower — November 24, 1998 on Mac, January 1999 on Windows — but the original stayed the one people remember: the game that made a generation of kids stare at real office elevators and silently judge their scheduling.
