RollerCoaster Tycoon and OpenTTD are both beloved 1990s-era tycoon games still played today. RollerCoaster Tycoon is about designing rides and running a theme park, single-player only; OpenTTD is an open-source recreation of Transport Tycoon with deep NewGRF modding and live multiplayer. Pick based on theme parks versus transport logistics.
Two classic 1990s tycoon-genre games, both still played today thanks to fan preservation — RollerCoaster Tycoon focuses on building and running a theme park, OpenTTD on building transport networks. Different systems, same era and spirit.

You want to design rides and manage guest happiness in a theme park, alone.
You want deep transport logistics with live multiplayer and one of the best long-term modding scenes in the genre.
RollerCoaster Tycoon turns tiny pricing decisions and hand-built hills into a park that feels alive, legible, and entirely yours.
OpenTTD is dangerously easy to underestimate. It looks like an old transport game, and then you realize you've spent two hours redesigning a rail network because one coal mine is producing more cargo than your entire system can handle. We picked it because its simple premise hides an absurdly satisfying optimization game.
