$44.99 ~25.9 hr median no co-op complexity: moderate 91.3% of 72k
The Squirrel's verdictPlanet Coaster centers on freeform, piece-by-piece construction: you sculpt terrain, lay paths manually, and place individual scenery objects rather than selecting presets. The park-management and budget layer is still present, but building depth is the main draw. Priced at $44.99, no co-op, with a median playtime around 26 hours and a Very Positive rating.
Not for you if you prefer fast, preset-driven building — Planet Coaster requires assembling structures element by element.

$5.99 ~28 hr median no co-op complexity: moderate 94.3% of 8k
The Squirrel's verdictRollerCoaster Tycoon Deluxe is the original RCT1 release: the same scenarios and park-management loop, with the classic desktop interface untouched. There's no built-in game-speed control, and reviewers note the executable needs workarounds to run on modern Windows. Rated Very Positive with a median playtime around 28 hours. Suits players who want the unaltered original over Classic's mobile-derived menus.
Not for you if you want game-speed controls built in or a version that runs without extra steps on modern Windows.

$29.99 ~56.4 hr median co-op complexity: moderate 94.2% of 8k
The Squirrel's verdictParkitect is a PC-native spiritual successor to RCT2 with deeper staff logistics, behind-the-scenes service path routing, and co-op play. Scenarios and the park-economy loop will feel familiar, but the added systems give experienced players more to manage. Rated Very Positive across a large review base, with a median playtime of around 56 hours.
Not for you if you rely on an undo button for building mistakes — Parkitect has none, and errors can require tearing out significant work.

$9.99 ~15 hr median no co-op complexity: moderate 89.6% of 6k
The Squirrel's verdictRollerCoaster Tycoon 2: Triple Thrill Pack delivers the original RCT2 desktop UI and its full scenario set at $9.99. The package is compatible with OpenRCT2, which reviewers consistently recommend for widescreen support and additional features — though some flag antivirus alerts from that software. Steam records a median of 15 hours, but several reviewers report 50–60 hours via OpenRCT2.
Not for you if you want a self-contained experience without third-party software to unlock widescreen and modern conveniences.

Thrillville®: Off the Rails™
PC
AdventureActionRacing
$9.99 ~10.1 hr median co-op complexity: light 93.1% of 927
The Squirrel's verdictThrillville: Off the Rails structures its park-sim around a story mode, character interaction, and visitor mini-games rather than open scenario management. Co-op play is supported. Median playtime sits at 10.1 hours — considerably shorter than a full tycoon scenario run. Reviewers note control and performance issues on modern systems, and some graphical options are needed to restore the original look.
Not for you if you want uninterrupted scenario-based park management without story missions or mini-games breaking up the building.

$19.99 ~15.8 hr median no co-op complexity: moderate 87.4% of 3k
The Squirrel's verdictRCT3 was built for mouse and keyboard from the start, adding a full 3D engine, in-cart camera rides, water parks, and zoo content not present in Classic. Reviewers note the UI does not scale above 1080p, making icons difficult to read at higher resolutions, though a manual file edit can adjust this. Priced at $19.99 with a Very Positive rating.
Not for you if you use a monitor above 1080p and don't want to edit game files — the UI does not scale natively and icons become hard to read.

Chris Sawyer's Locomotion™
PC
TrainsTransportationEconomy
$5.99 ~16.1 hr median no co-op complexity: moderate 86.7% of 667
The Squirrel's verdictChris Sawyer designed this after RCT, and the underlying loop — build networks, manage finances, watch systems operate — is recognizably related. The subject matter shifts entirely to trains, buses, planes, and cargo across open regions rather than park guests and coasters. The interface is unchanged since 2004, and resolution locks at 800×600.
Not for you if you want adjustable resolution or a modernized interface — the 800×600 lock and 2004-era menus are fixed.
